+4) Edit config.cfg to suit your needs (see [configuration](#configuration)). `acme-dns` will read the configuration file from `/etc/acme-dns/config.cfg` or `./config.cfg`, or a location specified with the `-c` flag.
 
-5) Run acme-dns. Please note that acme-dns needs to open a privileged port (53, domain), so it needs to be run with elevated privileges.
+5) If your system has systemd, you can optionally install acme-dns as a service so that it will start on boot and be tracked by systemd. This also allows us to add the `CAP_NET_BIND_SERVICE` capability so that acme-dns can be run by a user other than root.

+    1) Make sure that you have moved the configuration file to `/etc/acme-dns/config.cfg` so that acme-dns can access it globally.
 
-1) Pull the latest acme-dns Docker image: `docker pull joohoi/acme-dns` 
+    2) Move the acme-dns executable from `~/go/bin/acme-dns` to `/usr/local/bin/acme-dns` (Any location will work, just be sure to change `acme-dns.service` to match).
+
+    3) Create a minimal acme-dns user: `sudo adduser --system --gecos "acme-dns Service" --disabled-password --group --home /var/lib/acme-dns acme-dns`.
+
+    4) Move the systemd service unit from `acme-dns.service` to `/etc/systemd/system/acme-dns.service`.
+
+    5) Reload systemd units: `sudo systemctl daemon-reload`.
+
+    6) Enable acme-dns on boot: `sudo systemctl enable acme-dns.service`.
+
+    7) Run acme-dns: `sudo systemctl start acme-dns.service`.
+
+6) If you did not install the systemd service, run `acme-dns`. Please note that acme-dns needs to open a privileged port (53, domain), so it needs to be run with elevated privileges.

+
+## DNS Records
+
+Note: In this documentation:
+- `auth.example.org` is the hostname of the acme-dns server
+- acme-dns will serve `*.auth.example.org` records
+- `198.51.100.1` is the **public** IP address of the system running acme-dns  
+
+These values should be changed based on your environment.
+
+You will need to add some DNS records on your domain's regular DNS server:
+- `NS` record for `auth.example.org` pointing to `auth.example.org` (this means, that `auth.example.org` is responsible for any `*.auth.example.org` records)
+- `A` record for `auth.example.org` pointing to `198.51.100.1`
+- If using IPv6, an `AAAA` record pointing to the IPv6 address.
+- Each domain you will be authenticating will need a `_acme-challenge` `CNAME` subdomain added. The [client](README.md#clients) you use will explain how to do this.
+
+## Testing It Out
+
+You may want to test that acme-dns is working before using it for real queries.
+
+1) Confirm that DNS lookups for the acme-dns subdomain works as expected: `dig auth.example.org`.
+
+2) Call the `/register` API endpoint to register a test domain:
+```
+$ curl -X POST https://auth.example.org/register
+{"username":"eabcdb41-d89f-4580-826f-3e62e9755ef2","password":"pbAXVjlIOE01xbut7YnAbkhMQIkcwoHO0ek2j4Q0","fulldomain":"d420c923-bbd7-4056-ab64-c3ca54c9b3cf.auth.example.org","subdomain":"d420c923-bbd7-4056-ab64-c3ca54c9b3cf","allowfrom":[]}
+```
+
+3) Call the `/update` API endpoint to set a test TXT record. Pass the `username`, `password` and `subdomain` received from the `register` call performed above:
+```
+$ curl -X POST \
+  -H "X-Api-User: eabcdb41-d89f-4580-826f-3e62e9755ef2" \
+  -H "X-Api-Key: pbAXVjlIOE01xbut7YnAbkhMQIkcwoHO0ek2j4Q0" \
+  -d '{"subdomain": "d420c923-bbd7-4056-ab64-c3ca54c9b3cf", "txt": "___validation_token_received_from_the_ca___"}' \
+  https://auth.example.org/update
+```
+
+Note: The `txt` field must be exactly 43 characters long, otherwise acme-dns will reject it
+
+4) Perform a DNS lookup to the test subdomain to confirm the updated TXT record is being served:
+```
+$ dig -t txt @auth.example.org d420c923-bbd7-4056-ab64-c3ca54c9b3cf.auth.example.org
+```

+## HTTPS API
+
+The RESTful acme-dns API can be exposed over HTTPS in two ways:
+
+1. Using `tls = "letsencrypt"` and letting acme-dns issue its own certificate
+   automatically with Let's Encrypt.
+1. Using `tls = "cert"` and providing your own HTTPS certificate chain and
+   private key with `tls_cert_fullchain` and `tls_cert_privkey`.
+
+Where possible the first option is recommended. This is the easiest and safest
+way to have acme-dns expose its API over HTTPS.
+
+**Warning**: If you choose to use `tls = "cert"` you must take care that the
+certificate *does not expire*! If it does and the ACME client you use to issue the
+certificate depends on the ACME DNS API to update TXT records you will be stuck
+in a position where the API certificate has expired but it can't be renewed
+because the ACME client will refuse to connect to the ACME DNS API it needs to
+use for the renewal.

-## TOML parser and encoder for Go with reflection
-
-TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
-reflection interface similar to Go's standard library `json` and `xml`
-packages. This package also supports the `encoding.TextUnmarshaler` and
-`encoding.TextMarshaler` interfaces so that you can define custom data
-representations. (There is an example of this below.)
-
-Spec: https://github.com/toml-lang/toml
-
-Compatible with TOML version
-[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
-
-Documentation: https://godoc.org/github.com/BurntSushi/toml
-
-Installation:
-
-```bash
-go get github.com/BurntSushi/toml
-```
-
-Try the toml validator:
-
-```bash
-go get github.com/BurntSushi/toml/cmd/tomlv
-tomlv some-toml-file.toml
-```
-
-[![Build Status](https://travis-ci.org/BurntSushi/toml.svg?branch=master)](https://travis-ci.org/BurntSushi/toml) [![GoDoc](https://godoc.org/github.com/BurntSushi/toml?status.svg)](https://godoc.org/github.com/BurntSushi/toml)
-
-### Testing
-
-This package passes all tests in
-[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
-and the encoder.
-
-### Examples
-
-This package works similarly to how the Go standard library handles `XML`
-and `JSON`. Namely, data is loaded into Go values via reflection.
-
-For the simplest example, consider some TOML file as just a list of keys
-and values:
-
-```toml
-Age = 25
-Cats = [ "Cauchy", "Plato" ]
-Pi = 3.14
-Perfection = [ 6, 28, 496, 8128 ]
-DOB = 1987-07-05T05:45:00Z
-```
-
-Which could be defined in Go as:
-
-```go
-type Config struct {
-  Age int
-  Cats []string
-  Pi float64
-  Perfection []int
-  DOB time.Time // requires `import time`
-}
-```
-
-And then decoded with:
-
-```go
-var conf Config
-if _, err := toml.Decode(tomlData, &conf); err != nil {
-  // handle error
-}
-```
-
-You can also use struct tags if your struct field name doesn't map to a TOML
-key value directly:
-
-```toml
-some_key_NAME = "wat"
-```
-
-```go
-type TOML struct {
-  ObscureKey string `toml:"some_key_NAME"`
-}
-```
-
-### Using the `encoding.TextUnmarshaler` interface
-
-Here's an example that automatically parses duration strings into
-`time.Duration` values:
-
-```toml
-[[song]]
-name = "Thunder Road"
-duration = "4m49s"
-
-[[song]]
-name = "Stairway to Heaven"
-duration = "8m03s"
-```
-
-Which can be decoded with:
-
-```go
-type song struct {
-  Name     string
-  Duration duration
-}
-type songs struct {
-  Song []song
-}
-var favorites songs
-if _, err := toml.Decode(blob, &favorites); err != nil {
-  log.Fatal(err)
-}
-
-for _, s := range favorites.Song {
-  fmt.Printf("%s (%s)\n", s.Name, s.Duration)
-}
-```
-
-And you'll also need a `duration` type that satisfies the
-`encoding.TextUnmarshaler` interface:
-
-```go
-type duration struct {
-	time.Duration
-}
-
-func (d *duration) UnmarshalText(text []byte) error {
-	var err error
-	d.Duration, err = time.ParseDuration(string(text))
-	return err
-}
-```
-
-### More complex usage
-
-Here's an example of how to load the example from the official spec page:
-
-```toml
-# This is a TOML document. Boom.
-
-title = "TOML Example"
-
-[owner]
-name = "Tom Preston-Werner"
-organization = "GitHub"
-bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
-dob = 1979-05-27T07:32:00Z # First class dates? Why not?
-
-[database]
-server = "192.168.1.1"
-ports = [ 8001, 8001, 8002 ]
-connection_max = 5000
-enabled = true
-
-[servers]
-
-  # You can indent as you please. Tabs or spaces. TOML don't care.
-  [servers.alpha]
-  ip = "10.0.0.1"
-  dc = "eqdc10"
-
-  [servers.beta]
-  ip = "10.0.0.2"
-  dc = "eqdc10"
-
-[clients]
-data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
-
-# Line breaks are OK when inside arrays
-hosts = [
-  "alpha",
-  "omega"
-]
-```
-
-And the corresponding Go types are:
-
-```go
-type tomlConfig struct {
-	Title string
-	Owner ownerInfo
-	DB database `toml:"database"`
-	Servers map[string]server
-	Clients clients
-}
-
-type ownerInfo struct {
-	Name string
-	Org string `toml:"organization"`
-	Bio string
-	DOB time.Time
-}
-
-type database struct {
-	Server string
-	Ports []int
-	ConnMax int `toml:"connection_max"`
-	Enabled bool
-}
-
-type server struct {
-	IP string
-	DC string
-}
-
-type clients struct {
-	Data [][]interface{}
-	Hosts []string
-}
-```
-
-Note that a case insensitive match will be tried if an exact match can't be
-found.
-
-A working example of the above can be found in `_examples/example.{go,toml}`.

-Package toml provides facilities for decoding and encoding TOML configuration

-MetaData type.
-
-The specification implemented: https://github.com/toml-lang/toml
-
-The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
-whether a file is a valid TOML document. It can also be used to print the

-
-Testing
-
-There are two important types of tests used for this package. The first is
-contained inside '*_test.go' files and uses the standard Go unit testing
-framework. These tests are primarily devoted to holistically testing the
-decoder and encoder.
-
-The second type of testing is used to verify the implementation's adherence
-to the TOML specification. These tests have been factored into their own
-project: https://github.com/BurntSushi/toml-test
-
-The reason the tests are in a separate project is so that they can be used by
-any implementation of TOML. Namely, it is language agnostic.

-A Form Encoding & Decoding Package for Go, written by [Alvaro J. Genial](http://alva.ro).
-
-[![Build Status](https://travis-ci.org/ajg/form.png?branch=master)](https://travis-ci.org/ajg/form)
-[![GoDoc](https://godoc.org/github.com/ajg/form?status.png)](https://godoc.org/github.com/ajg/form)
-
-Synopsis
---------
-
-This library is designed to allow seamless, high-fidelity encoding and decoding of arbitrary data in `application/x-www-form-urlencoded` format and as [`url.Values`](http://golang.org/pkg/net/url/#Values). It is intended to be useful primarily in dealing with web forms and URI query strings, both of which natively employ said format.
-
-Unsurprisingly, `form` is modeled after other Go [`encoding`](http://golang.org/pkg/encoding/) packages, in particular [`encoding/json`](http://golang.org/pkg/encoding/json/), and follows the same conventions (see below for more.) It aims to automatically handle any kind of concrete Go [data value](#values) (i.e., not functions, channels, etc.) while providing mechanisms for custom behavior.
-
-Status
-------
-
-The implementation is in usable shape and is fairly well tested with its accompanying test suite. The API is unlikely to change much, but still may. Lastly, the code has not yet undergone a security review to ensure it is free of vulnerabilities. Please file an issue or send a pull request for fixes & improvements.
-
-Dependencies
-------------
-
-The only requirement is [Go 1.2](http://golang.org/doc/go1.2) or later.
-
-Usage
------
-
-```go
-import "github.com/ajg/form"
-```
-
-Given a type like the following...
-
-```go
-type User struct {
-	Name         string            `form:"name"`
-	Email        string            `form:"email"`
-	Joined       time.Time         `form:"joined,omitempty"`
-	Posts        []int             `form:"posts"`
-	Preferences  map[string]string `form:"prefs"`
-	Avatar       []byte            `form:"avatar"`
-	PasswordHash int64             `form:"-"`
-}
-```
-
-...it is easy to encode data of that type...
-
-
-```go
-func PostUser(url string, u User) error {
-	var c http.Client
-	_, err := c.PostForm(url, form.EncodeToValues(u))
-	return err
-}
-```
-
-...as well as decode it...
-
-
-```go
-func Handler(w http.ResponseWriter, r *http.Request) {
-	var u User
-
-	d := form.NewDecoder(r.Body)
-	if err := d.Decode(&u); err != nil {
-		http.Error(w, "Form could not be decoded", http.StatusBadRequest)
-		return
-	}
-
-	fmt.Fprintf(w, "Decoded: %#v", u)
-}
-```
-
-...without having to do any grunt work.
-
-Field Tags
-----------
-
-Like other encoding packages, `form` supports the following options for fields:
-
- - `` `form:"-"` ``: Causes the field to be ignored during encoding and decoding.
- - `` `form:"<name>"` ``: Overrides the field's name; useful especially when dealing with external identifiers in camelCase, as are commonly found on the web.
- - `` `form:",omitempty"` ``: Elides the field during encoding if it is empty (typically meaning equal to the type's zero value.)
- - `` `form:"<name>,omitempty"` ``: The way to combine the two options above.
-
-Values
-------
-
-### Simple Values
-
-Values of the following types are all considered simple:
-
- - `bool`
- - `int`, `int8`, `int16`, `int32`, `int64`, `rune`
- - `uint`, `uint8`, `uint16`, `uint32`, `uint64`, `byte`
- - `float32`, `float64`
- - `complex64`, `complex128`
- - `string`
- - `[]byte` (see note)
- - [`time.Time`](http://golang.org/pkg/time/#Time)
- - [`url.URL`](http://golang.org/pkg/net/url/#URL)
- - An alias of any of the above
- - A pointer to any of the above
-
-### Composite Values
-
-A composite value is one that can contain other values. Values of the following kinds...
-
- - Maps
- - Slices; except `[]byte` (see note)
- - Structs; except [`time.Time`](http://golang.org/pkg/time/#Time) and [`url.URL`](http://golang.org/pkg/net/url/#URL)
- - Arrays
- - An alias of any of the above
- - A pointer to any of the above
-
-...are considered composites in general, unless they implement custom marshaling/unmarshaling. Composite values are encoded as a flat mapping of paths to values, where the paths are constructed by joining the parent and child paths with a period (`.`).
-
-(Note: a byte slice is treated as a `string` by default because it's more efficient, but can also be decoded as a slice—i.e., with indexes.)
-
-### Untyped Values
-
-While encouraged, it is not necessary to define a type (e.g. a `struct`) in order to use `form`, since it is able to encode and decode untyped data generically using the following rules:
-
- - Simple values will be treated as a `string`.
- - Composite values will be treated as a `map[string]interface{}`, itself able to contain nested values (both scalar and compound) ad infinitum.
- - However, if there is a value (of any supported type) already present in a map for a given key, then it will be used when possible, rather than being replaced with a generic value as specified above; this makes it possible to handle partially typed, dynamic or schema-less values.
-
-### Zero Values
-
-By default, and without custom marshaling, zero values (also known as empty/default values) are encoded as the empty string. To disable this behavior, meaning to keep zero values in their literal form (e.g. `0` for integral types), `Encoder` offers a `KeepZeros` setter method, which will do just that when set to `true`.
-
-### Unsupported Values
-
-Values of the following kinds aren't supported and, if present, must be ignored.
-
- - Channel
- - Function
- - Unsafe pointer
- - An alias of any of the above
- - A pointer to any of the above
-
-Custom Marshaling
------------------
-
-There is a default (generally lossless) marshaling & unmarshaling scheme for any concrete data value in Go, which is good enough in most cases. However, it is possible to override it and use a custom scheme. For instance, a "binary" field could be marshaled more efficiently using [base64](http://golang.org/pkg/encoding/base64/) to prevent it from being percent-escaped during serialization to `application/x-www-form-urlencoded` format.
-
-Because `form` provides support for [`encoding.TextMarshaler`](http://golang.org/pkg/encoding/#TextMarshaler) and [`encoding.TextUnmarshaler`](http://golang.org/pkg/encoding/#TextUnmarshaler) it is easy to do that; for instance, like this:
-
-```go
-import "encoding"
-
-type Binary []byte
-
-var (
-	_ encoding.TextMarshaler   = &Binary{}
-	_ encoding.TextUnmarshaler = &Binary{}
-)
-
-func (b Binary) MarshalText() ([]byte, error) {
-	return []byte(base64.URLEncoding.EncodeToString([]byte(b))), nil
-}
-
-func (b *Binary) UnmarshalText(text []byte) error {
-	bs, err := base64.URLEncoding.DecodeString(string(text))
-	if err == nil {
-		*b = Binary(bs)
-	}
-	return err
-}
-```
-
-Now any value with type `Binary` will automatically be encoded using the [URL](http://golang.org/pkg/encoding/base64/#URLEncoding) variant of base64. It is left as an exercise to the reader to improve upon this scheme by eliminating the need for padding (which, besides being superfluous, uses `=`, a character that will end up percent-escaped.)
-
-Keys
-----
-
-In theory any value can be a key as long as it has a string representation. However, by default, periods have special meaning to `form`, and thus, under the hood (i.e. in encoded form) they are transparently escaped using a preceding backslash (`\`). Backslashes within keys, themselves, are also escaped in this manner (e.g. as `\\`) in order to permit representing `\.` itself (as `\\\.`).
-
-(Note: it is normally unnecessary to deal with this issue unless keys are being constructed manually—e.g. literally embedded in HTML or in a URI.)
-
-The default delimiter and escape characters used for encoding and decoding composite keys can be changed using the `DelimitWith` and `EscapeWith` setter methods of `Encoder` and `Decoder`, respectively. For example...
-
-```go
-package main
-
-import (
-	"os"
-
-	"github.com/ajg/form"
-)
-
-func main() {
-	type B struct {
-		Qux string `form:"qux"`
-	}
-	type A struct {
-		FooBar B `form:"foo.bar"`
-	}
-	a := A{FooBar: B{"XYZ"}}
-	os.Stdout.WriteString("Default: ")
-	form.NewEncoder(os.Stdout).Encode(a)
-	os.Stdout.WriteString("\nCustom:  ")
-	form.NewEncoder(os.Stdout).DelimitWith('/').Encode(a)
-	os.Stdout.WriteString("\n")
-}
-
-```
-
-...will produce...
-
-```
-Default: foo%5C.bar.qux=XYZ
-Custom:  foo.bar%2Fqux=XYZ
-```
-
-(`%5C` and `%2F` represent `\` and `/`, respectively.)
-
-Limitations
------------
-
- - Circular (self-referential) values are untested.
-
-Future Work
------------
-
-The following items would be nice to have in the future—though they are not being worked on yet:
-
- - An option to treat all values as if they had been tagged with `omitempty`.
- - An option to automatically treat all field names in `camelCase` or `underscore_case`.
- - Built-in support for the types in [`math/big`](http://golang.org/pkg/math/big/).
- - Built-in support for the types in [`image/color`](http://golang.org/pkg/image/color/).
- - Improve encoding/decoding by reading/writing directly from/to the `io.Reader`/`io.Writer` when possible, rather than going through an intermediate representation (i.e. `node`) which requires more memory.
-
-(Feel free to implement any of these and then send a pull request.)
-
-Related Work
-------------
-
- - Package [gorilla/schema](https://github.com/gorilla/schema), which only implements decoding.
- - Package [google/go-querystring](https://github.com/google/go-querystring), which only implements encoding.

-(https://coveralls.io/r/davecgh/go-spew?branch=master)
-
-
-Go-spew implements a deep pretty printer for Go data structures to aid in
-debugging.  A comprehensive suite of tests with 100% test coverage is provided
-to ensure proper functionality.  See `test_coverage.txt` for the gocov coverage
-report.  Go-spew is licensed under the liberal ISC license, so it may be used in
-open source or commercial projects.
-
-If you're interested in reading about how this package came to life and some
-of the challenges involved in providing a deep pretty printer, there is a blog
-post about it
-[here](https://web.archive.org/web/20160304013555/https://blog.cyphertite.com/go-spew-a-journey-into-dumping-go-data-structures/).
-
-## Documentation
-
-[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)]
-(http://godoc.org/github.com/davecgh/go-spew/spew)
-
-Full `go doc` style documentation for the project can be viewed online without
-installing this package by using the excellent GoDoc site here:
-http://godoc.org/github.com/davecgh/go-spew/spew
-
-You can also view the documentation locally once the package is installed with
-the `godoc` tool by running `godoc -http=":6060"` and pointing your browser to
-http://localhost:6060/pkg/github.com/davecgh/go-spew/spew
-
-## Installation
-
-```bash
-$ go get -u github.com/davecgh/go-spew/spew
-```
-
-## Quick Start
-
-Add this import line to the file you're working in:
-
-```Go
-import "github.com/davecgh/go-spew/spew"
-```
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
-
-```Go
-spew.Dump(myVar1, myVar2, ...)
-spew.Fdump(someWriter, myVar1, myVar2, ...)
-str := spew.Sdump(myVar1, myVar2, ...)
-```
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with %v (most
-compact), %+v (adds pointer addresses), %#v (adds types), or %#+v (adds types
-and pointer addresses): 
-
-```Go
-spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-```
-
-## Debugging a Web Application Example
-
-Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
-
-```Go
-package main
-
-import (
-    "fmt"
-    "html"
-    "net/http"
-
-    "github.com/davecgh/go-spew/spew"
-)
-
-func handler(w http.ResponseWriter, r *http.Request) {
-    w.Header().Set("Content-Type", "text/html")
-    fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
-    fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
-}
-
-func main() {
-    http.HandleFunc("/", handler)
-    http.ListenAndServe(":8080", nil)
-}
-```
-
-## Sample Dump Output
-
-```
-(main.Foo) {
- unexportedField: (*main.Bar)(0xf84002e210)({
-  flag: (main.Flag) flagTwo,
-  data: (uintptr) <nil>
- }),
- ExportedField: (map[interface {}]interface {}) {
-  (string) "one": (bool) true
- }
-}
-([]uint8) {
- 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
- 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
- 00000020  31 32                                             |12|
-}
-```
-
-## Sample Formatter Output
-
-Double pointer to a uint8:
-```
-	  %v: <**>5
-	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
-	 %#v: (**uint8)5
-	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-```
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
-```
-	  %v: <*>{1 <*><shown>}
-	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
-	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
-	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
-```
-
-## Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type. For
-convenience, all of the top-level functions use a global state available via the
-spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions. This allows concurrent configuration
-options. See the ConfigState documentation for more details.
-
-```
-* Indent
-	String to use for each indentation level for Dump functions.
-	It is a single space by default.  A popular alternative is "\t".
-
-* MaxDepth
-	Maximum number of levels to descend into nested data structures.
-	There is no limit by default.
-
-* DisableMethods
-	Disables invocation of error and Stringer interface methods.
-	Method invocation is enabled by default.
-
-* DisablePointerMethods
-	Disables invocation of error and Stringer interface methods on types
-	which only accept pointer receivers from non-pointer variables.  This option
-	relies on access to the unsafe package, so it will not have any effect when
-	running in environments without access to the unsafe package such as Google
-	App Engine or with the "safe" build tag specified.
-	Pointer method invocation is enabled by default.
-
-* DisablePointerAddresses
-	DisablePointerAddresses specifies whether to disable the printing of
-	pointer addresses. This is useful when diffing data structures in tests.
-
-* DisableCapacities
-	DisableCapacities specifies whether to disable the printing of capacities
-	for arrays, slices, maps and channels. This is useful when diffing data
-	structures in tests.
-
-* ContinueOnMethod
-	Enables recursion into types after invoking error and Stringer interface
-	methods. Recursion after method invocation is disabled by default.
-
-* SortKeys
-	Specifies map keys should be sorted before being printed. Use
-	this to have a more deterministic, diffable output.  Note that
-	only native types (bool, int, uint, floats, uintptr and string)
-	and types which implement error or Stringer interfaces are supported,
-	with other types sorted according to the reflect.Value.String() output
-	which guarantees display stability.  Natural map order is used by
-	default.
-
-* SpewKeys
-	SpewKeys specifies that, as a last resort attempt, map keys should be
-	spewed to strings and sorted by those strings.  This is only considered
-	if SortKeys is true.
-
-```
-
-## Unsafe Package Dependency
-
-This package relies on the unsafe package to perform some of the more advanced
-features, however it also supports a "limited" mode which allows it to work in
-environments where the unsafe package is not available.  By default, it will
-operate in this mode on Google App Engine and when compiled with GopherJS.  The
-"safe" build tag may also be specified to force the package to build without
-using the unsafe package.

-Package spew implements a deep pretty printer for Go data structures to aid in
-debugging.
-
-A quick overview of the additional features spew provides over the built-in
-printing facilities for Go data types are as follows:
-
-	* Pointers are dereferenced and followed
-	* Circular data structures are detected and handled properly
-	* Custom Stringer/error interfaces are optionally invoked, including
-	  on unexported types
-	* Custom types which only implement the Stringer/error interfaces via
-	  a pointer receiver are optionally invoked when passing non-pointer
-	  variables
-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output (only when using
-	  Dump style)
-
-There are two different approaches spew allows for dumping Go data structures:
-
-	* Dump style which prints with newlines, customizable indentation,
-	  and additional debug information such as types and all pointer addresses
-	  used to indirect to the final value
-	* A custom Formatter interface that integrates cleanly with the standard fmt
-	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
-	  similar to the default %v while providing the additional functionality
-	  outlined above and passing unsupported format verbs such as %x and %q
-	  along to fmt
-
-Quick Start
-
-This section demonstrates how to quickly get started with spew.  See the
-sections below for further details on formatting and configuration options.
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
-	spew.Dump(myVar1, myVar2, ...)
-	spew.Fdump(someWriter, myVar1, myVar2, ...)
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with
-%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
-%#+v (adds types and pointer addresses):
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type.  For
-convenience, all of the top-level functions use a global state available
-via the spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions.  This allows concurrent configuration
-options.  See the ConfigState documentation for more details.
-
-The following configuration options are available:
-	* Indent
-		String to use for each indentation level for Dump functions.
-		It is a single space by default.  A popular alternative is "\t".
-
-	* MaxDepth
-		Maximum number of levels to descend into nested data structures.
-		There is no limit by default.
-
-	* DisableMethods
-		Disables invocation of error and Stringer interface methods.
-		Method invocation is enabled by default.
-
-	* DisablePointerMethods
-		Disables invocation of error and Stringer interface methods on types
-		which only accept pointer receivers from non-pointer variables.
-		Pointer method invocation is enabled by default.
-
-	* DisablePointerAddresses
-		DisablePointerAddresses specifies whether to disable the printing of
-		pointer addresses. This is useful when diffing data structures in tests.
-
-	* DisableCapacities
-		DisableCapacities specifies whether to disable the printing of
-		capacities for arrays, slices, maps and channels. This is useful when
-		diffing data structures in tests.
-
-	* ContinueOnMethod
-		Enables recursion into types after invoking error and Stringer interface
-		methods. Recursion after method invocation is disabled by default.
-
-	* SortKeys
-		Specifies map keys should be sorted before being printed. Use
-		this to have a more deterministic, diffable output.  Note that
-		only native types (bool, int, uint, floats, uintptr and string)
-		and types which implement error or Stringer interfaces are
-		supported with other types sorted according to the
-		reflect.Value.String() output which guarantees display
-		stability.  Natural map order is used by default.
-
-	* SpewKeys
-		Specifies that, as a last resort attempt, map keys should be
-		spewed to strings and sorted by those strings.  This is only
-		considered if SortKeys is true.
-
-Dump Usage
-
-Simply call spew.Dump with a list of variables you want to dump:
-
-	spew.Dump(myVar1, myVar2, ...)
-
-You may also call spew.Fdump if you would prefer to output to an arbitrary
-io.Writer.  For example, to dump to standard error:
-
-	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
-
-A third option is to call spew.Sdump to get the formatted output as a string:
-
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Sample Dump Output
-
-See the Dump example for details on the setup of the types and variables being
-shown here.
-
-	(main.Foo) {
-	 unexportedField: (*main.Bar)(0xf84002e210)({
-	  flag: (main.Flag) flagTwo,
-	  data: (uintptr) <nil>
-	 }),
-	 ExportedField: (map[interface {}]interface {}) (len=1) {
-	  (string) (len=3) "one": (bool) true
-	 }
-	}
-
-Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
-command as shown.
-	([]uint8) (len=32 cap=32) {
-	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
-	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
-	 00000020  31 32                                             |12|
-	}
-
-Custom Formatter
-
-Spew provides a custom formatter that implements the fmt.Formatter interface
-so that it integrates cleanly with standard fmt package printing functions. The
-formatter is useful for inline printing of smaller data types similar to the
-standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Custom Formatter Usage
-
-The simplest way to make use of the spew custom formatter is to call one of the
-convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
-functions have syntax you are most likely already familiar with:
-
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Println(myVar, myVar2)
-	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-See the Index for the full list convenience functions.
-
-Sample Formatter Output
-
-Double pointer to a uint8:
-	  %v: <**>5
-	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
-	 %#v: (**uint8)5
-	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
-	  %v: <*>{1 <*><shown>}
-	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
-	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
-	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
-
-See the Printf example for details on the setup of variables being shown
-here.
-
-Errors
-
-Since it is possible for custom Stringer/error interfaces to panic, spew
-detects them and handles them internally by printing the panic information
-inline with the output.  Since spew is intended to provide deep pretty printing
-capabilities on structures, it intentionally does not return any errors.

-package:
-
-	* Pointers are dereferenced and followed
-	* Circular data structures are detected and handled properly
-	* Custom Stringer/error interfaces are optionally invoked, including
-	  on unexported types
-	* Custom types which only implement the Stringer/error interfaces via
-	  a pointer receiver are optionally invoked when passing non-pointer
-	  variables
-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output
-
-The configuration options are controlled by an exported package global,
-spew.Config.  See ConfigState for options documentation.
-
-See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
-get the formatted result as a string.

-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
