-### Modifying campaign GitHub labels
-
-`campaigner` can add labels to the GitHub tickets when creating them. Labels can be added to the campaign as part of the `init` command, but they can be managed as well when the campaign is already created with the `campaigner label` commands:
-
- - `campaigner label list` lists the current campaign labels.
- - `campaigner label remote` lists the labels that exist in the remote GitHub repository.
- - `campaigner label update` opens `$EDITOR` with the campaign labels and allows you to add / remove / edit them, saving them when the editor closes. It will error if a label doesn't exist in the remote repository, but you can skip this check adding the `--skip-check` flag.
-
 ### Adding tickets to the campaign
 
 There are currently three ways to add tickets to a campaign: using `govet`, using `grep` or importing a `csv`. We can add tickets at any point during the campaign lifecycle, and we can use different methods in the same campaign, just remember that the summary and the templates will be filled with whatever properties we have in each ticket, so all of them should have at least those used in the templates.

 Once the campaign is ready, we can see its status running `campaigner status`:
 
 ```sh

-         67     -         total tickets

-         24   35%     published in Jira
+        0/351   published in Jira
-         24   35%   published in Github
+        0/0     published in Github

-          0    0%                closed
 
 ```
 
 The status shows the total of tickets that we have created, how many of those have been published in Jira and of that last amount, how many have been published in GitHub too.
 
 To publish tickets, you can use the `campaigner publish jira` and `campaigner publish github` commands, and you can publish tickets in batches or just publish all of them. When running a publish command, `campaigner` will search the first unpublished tickets and will use the provider APIs to publish them.
-
-### Syncing the campaign status
-
-If we want to check the status of our campaign as it progresses and the tickets get assigned and closed, we have first to sync our local state of the campaign with the status of the tickets we've published:
-
-```sh
-$ campaigner sync
-Updating ticket 9 of 9
-Synchronization completed
-```
-
-This will fetch the current state of the jira tickets and github issues and update our local campaign. Then we can run `campaigner status` to see the updated progress, or we can generate reports from the campaign's information with `campaigner report`.

+## JIRA to MarkDown text format converter
+Golang tool to convert from JIRA Markdown text formatting to GitHub Flavored MarkDown.
+
+## Credits
+This fun toy was heavily inspired by the J2M project by Fokke Zandbergen (http://j2m.fokkezb.nl/). Major credit to Fokke, kylefarris (and other contributors) for establishing the RexExp patterns for this to work. The maintained JavaScript fork I based this on is [here](https://github.com/kylefarris/J2M)
+
+## Supported Conversions
+
+* Headers (H1-H6)
+* Bold
+* Italic
+* Bold + Italic
+* Un-ordered lists
+* Ordered lists
+* Programming Language-specific code blocks (with help from herbert-venancio)
+* Inline preformatted text spans
+* Un-named links
+* Named links
+* Monospaced Text
+* ~~Citations~~ (currently kinda buggy)
+* Strikethroughs
+* Inserts
+* Superscripts
+* Subscripts
+* Single-paragraph blockquotes
+* Tables
+* Panels
+
+
+## How to Use
+
+### Markdown String
+
+```
+**Some bold things**
+*Some italic stuff*
+## H2
+<http://google.com>
+```
+
+### Atlassian Wiki MarkUp Syntax (JIRA)
+
+We'll refer to this as the `jira` variable in the examples below.

+# Color [![GoDoc](https://godoc.org/github.com/fatih/color?status.svg)](https://godoc.org/github.com/fatih/color) 
+
+Color lets you use colorized outputs in terms of [ANSI Escape
+Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It
+has support for Windows too! The API can be used in several ways, pick one that
+suits you.
+
+
+![Color](https://i.imgur.com/c1JI0lA.png)
+
+
+## Install
+
+```bash
+go get github.com/fatih/color
+```
+
+## Examples
+
+### Standard colors
+
+```go
+// Print with default helper functions
+color.Cyan("Prints text in cyan.")
+
+// A newline will be appended automatically
+color.Blue("Prints %s in blue.", "text")
+
+// These are using the default foreground colors
+color.Red("We have red")
+color.Magenta("And many others ..")
+
+```
+
+### Mix and reuse colors
+
+```go
+// Create a new color object
+c := color.New(color.FgCyan).Add(color.Underline)
+c.Println("Prints cyan text with an underline.")
+
+// Or just add them to New()
+d := color.New(color.FgCyan, color.Bold)
+d.Printf("This prints bold cyan %s\n", "too!.")
+
+// Mix up foreground and background colors, create new mixes!
+red := color.New(color.FgRed)
+
+boldRed := red.Add(color.Bold)
+boldRed.Println("This will print text in bold red.")
+
+whiteBackground := red.Add(color.BgWhite)
+whiteBackground.Println("Red text with white background.")
+```
+
+### Use your own output (io.Writer)
+
+```go
+// Use your own io.Writer output
+color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
+
+blue := color.New(color.FgBlue)
+blue.Fprint(writer, "This will print text in blue.")
+```
+
+### Custom print functions (PrintFunc)
+
+```go
+// Create a custom print function for convenience
+red := color.New(color.FgRed).PrintfFunc()
+red("Warning")
+red("Error: %s", err)
+
+// Mix up multiple attributes
+notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+notice("Don't forget this...")
+```
+
+### Custom fprint functions (FprintFunc)
+
+```go
+blue := color.New(FgBlue).FprintfFunc()
+blue(myWriter, "important notice: %s", stars)
+
+// Mix up with multiple attributes
+success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
+success(myWriter, "Don't forget this...")
+```
+
+### Insert into noncolor strings (SprintFunc)
+
+```go
+// Create SprintXxx functions to mix strings with other non-colorized strings:
+yellow := color.New(color.FgYellow).SprintFunc()
+red := color.New(color.FgRed).SprintFunc()
+fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
+fmt.Printf("This %s rocks!\n", info("package"))
+
+// Use helper functions
+fmt.Println("This", color.RedString("warning"), "should be not neglected.")
+fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
+
+// Windows supported too! Just don't forget to change the output to color.Output
+fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+```
+
+### Plug into existing code
+
+```go
+// Use handy standard colors
+color.Set(color.FgYellow)
+
+fmt.Println("Existing text will now be in yellow")
+fmt.Printf("This one %s\n", "too")
+
+color.Unset() // Don't forget to unset
+
+// You can mix up parameters
+color.Set(color.FgMagenta, color.Bold)
+defer color.Unset() // Use it in your function
+
+fmt.Println("All text will now be bold magenta.")
+```
+
+### Disable/Enable color
+ 
+There might be a case where you want to explicitly disable/enable color output. the 
+`go-isatty` package will automatically disable color output for non-tty output streams 
+(for example if the output were piped directly to `less`)
+
+`Color` has support to disable/enable colors both globally and for single color 
+definitions. For example suppose you have a CLI app and a `--no-color` bool flag. You 
+can easily disable the color output with:
+
+```go
+
+var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+
+if *flagNoColor {
+	color.NoColor = true // disables colorized output
+}
+```
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+```go
+c := color.New(color.FgCyan)
+c.Println("Prints cyan text")
+
+c.DisableColor()
+c.Println("This is printed without any color")
+
+c.EnableColor()
+c.Println("This prints again cyan...")
+```

+Package color is an ANSI color package to output colorized or SGR defined
+output to the standard output. The API can be used in several way, pick one
+that suits you.
+
+Use simple and default helper functions with predefined foreground colors:
+
+    color.Cyan("Prints text in cyan.")
+
+    // a newline will be appended automatically
+    color.Blue("Prints %s in blue.", "text")
+
+    // More default foreground colors..
+    color.Red("We have red")
+    color.Yellow("Yellow color too!")
+    color.Magenta("And many others ..")
+
+    // Hi-intensity colors
+    color.HiGreen("Bright green color.")
+    color.HiBlack("Bright black means gray..")
+    color.HiWhite("Shiny white color!")
+
+However there are times where custom color mixes are required. Below are some
+examples to create custom color objects and use the print functions of each
+separate color object.
+
+    // Create a new color object
+    c := color.New(color.FgCyan).Add(color.Underline)
+    c.Println("Prints cyan text with an underline.")
+
+    // Or just add them to New()
+    d := color.New(color.FgCyan, color.Bold)
+    d.Printf("This prints bold cyan %s\n", "too!.")
+
+
+    // Mix up foreground and background colors, create new mixes!
+    red := color.New(color.FgRed)
+
+    boldRed := red.Add(color.Bold)
+    boldRed.Println("This will print text in bold red.")
+
+    whiteBackground := red.Add(color.BgWhite)
+    whiteBackground.Println("Red text with White background.")
+
+    // Use your own io.Writer output
+    color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
+
+    blue := color.New(color.FgBlue)
+    blue.Fprint(myWriter, "This will print text in blue.")
+
+You can create PrintXxx functions to simplify even more:
+
+    // Create a custom print function for convenient
+    red := color.New(color.FgRed).PrintfFunc()
+    red("warning")
+    red("error: %s", err)
+
+    // Mix up multiple attributes
+    notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+    notice("don't forget this...")
+
+You can also FprintXxx functions to pass your own io.Writer:
+
+    blue := color.New(FgBlue).FprintfFunc()
+    blue(myWriter, "important notice: %s", stars)
+
+    // Mix up with multiple attributes
+    success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
+    success(myWriter, don't forget this...")
+
+
+Or create SprintXxx functions to mix strings with other non-colorized strings:
+
+    yellow := New(FgYellow).SprintFunc()
+    red := New(FgRed).SprintFunc()
+
+    fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+    info := New(FgWhite, BgGreen).SprintFunc()
+    fmt.Printf("this %s rocks!\n", info("package"))
+
+Windows support is enabled by default. All Print functions work as intended.
+However only for color.SprintXXX functions, user should use fmt.FprintXXX and
+set the output to color.Output:
+
+    fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+
+    info := New(FgWhite, BgGreen).SprintFunc()
+    fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
+
+Using with existing code is possible. Just use the Set() method to set the
+standard output to the given parameters. That way a rewrite of an existing
+code is not required.
+
+    // Use handy standard colors.
+    color.Set(color.FgYellow)
+
+    fmt.Println("Existing text will be now in Yellow")
+    fmt.Printf("This one %s\n", "too")
+
+    color.Unset() // don't forget to unset
+
+    // You can mix up parameters
+    color.Set(color.FgMagenta, color.Bold)
+    defer color.Unset() // use it in your function
+
+    fmt.Println("All text will be now bold magenta.")
+
+There might be a case where you want to disable color output (for example to
+pipe the standard output of your app to somewhere else). `Color` has support to
+disable colors both globally and for single color definition. For example
+suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
+the color output with:
+
+    var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+
+    if *flagNoColor {
+    	color.NoColor = true // disables colorized output
+    }
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+     c := color.New(color.FgCyan)
+     c.Println("Prints cyan text")
+
+     c.DisableColor()
+     c.Println("This is printed without any color")
+
+     c.EnableColor()
+     c.Println("This prints again cyan...")

+
+Structs contains various utilities to work with Go (Golang) structs. It was
+initially used by me to convert a struct into a `map[string]interface{}`. With
+time I've added other utilities for structs.  It's basically a high level
+package based on primitives from the reflect package. Feel free to add new
+functions or improve the existing code.
+
+## Install
+
+```bash
+go get github.com/fatih/structs
+```
+
+## Usage and Examples
+
+Just like the standard lib `strings`, `bytes` and co packages, `structs` has
+many global functions to manipulate or organize your struct data. Lets define
+and declare a struct:
+
+```go
+type Server struct {
+	Name        string `json:"name,omitempty"`
+	ID          int
+	Enabled     bool
+	users       []string // not exported
+	http.Server          // embedded
+}
+
+server := &Server{
+	Name:    "gopher",
+	ID:      123456,
+	Enabled: true,
+}
+```
+
+```go
+// Convert a struct to a map[string]interface{}
+// => {"Name":"gopher", "ID":123456, "Enabled":true}
+m := structs.Map(server)
+
+// Convert the values of a struct to a []interface{}
+// => ["gopher", 123456, true]
+v := structs.Values(server)
+
+// Convert the names of a struct to a []string
+// (see "Names methods" for more info about fields)
+n := structs.Names(server)
+
+// Convert the values of a struct to a []*Field
+// (see "Field methods" for more info about fields)
+f := structs.Fields(server)
+
+// Return the struct name => "Server"
+n := structs.Name(server)
+
+// Check if any field of a struct is initialized or not.
+h := structs.HasZero(server)
+
+// Check if all fields of a struct is initialized or not.
+z := structs.IsZero(server)
+
+// Check if server is a struct or a pointer to struct
+i := structs.IsStruct(server)
+```
+
+### Struct methods
+
+The structs functions can be also used as independent methods by creating a new
+`*structs.Struct`. This is handy if you want to have more control over the
+structs (such as retrieving a single Field).
+
+```go
+// Create a new struct type:
+s := structs.New(server)
+
+m := s.Map()              // Get a map[string]interface{}
+v := s.Values()           // Get a []interface{}
+f := s.Fields()           // Get a []*Field
+n := s.Names()            // Get a []string
+f := s.Field(name)        // Get a *Field based on the given field name
+f, ok := s.FieldOk(name)  // Get a *Field based on the given field name
+n := s.Name()             // Get the struct name
+h := s.HasZero()          // Check if any field is uninitialized
+z := s.IsZero()           // Check if all fields are uninitialized
+```
+
+### Field methods
+
+We can easily examine a single Field for more detail. Below you can see how we
+get and interact with various field methods:
+
+
+```go
+s := structs.New(server)
+
+// Get the Field struct for the "Name" field
+name := s.Field("Name")
+
+// Get the underlying value,  value => "gopher"
+value := name.Value().(string)
+
+// Set the field's value
+name.Set("another gopher")
+
+// Get the field's kind, kind =>  "string"
+name.Kind()
+
+// Check if the field is exported or not
+if name.IsExported() {
+	fmt.Println("Name field is exported")
+}
+
+// Check if the value is a zero value, such as "" for string, 0 for int
+if !name.IsZero() {
+	fmt.Println("Name is initialized")
+}
+
+// Check if the field is an anonymous (embedded) field
+if !name.IsEmbedded() {
+	fmt.Println("Name is not an embedded field")
+}
+
+// Get the Field's tag value for tag name "json", tag value => "name,omitempty"
+tagValue := name.Tag("json")
+```
+
+Nested structs are supported too:
+
+```go
+addrField := s.Field("Server").Field("Addr")
+
+// Get the value for addr
+a := addrField.Value().(string)
+
+// Or get all fields
+httpServer := s.Field("Server").Fields()
+```
+
+We can also get a slice of Fields from the Struct type to iterate over all
+fields. This is handy if you wish to examine all fields:
+
+```go
+s := structs.New(server)
+
+for _, f := range s.Fields() {
+	fmt.Printf("field name: %+v\n", f.Name())
+
+	if f.IsExported() {
+		fmt.Printf("value   : %+v\n", f.Value())
+		fmt.Printf("is zero : %+v\n", f.IsZero())
+	}
+}
+```

+Equal returns true iff protocol buffers a and b are equal.
+The arguments must both be pointers to protocol buffer structs.

+Equality is defined in this way:
+  - Two messages are equal iff they are the same type,
+    corresponding fields are equal, unknown field sets
+    are equal, and extensions sets are equal.
+  - Two set scalar fields are equal iff their values are equal.
+    If the fields are of a floating-point type, remember that
+    NaN != x for all x, including NaN. If the message is defined
+    in a proto3 .proto file, fields are not "set"; specifically,
+    zero length proto3 "bytes" fields are equal (nil == {}).
+  - Two repeated fields are equal iff their lengths are the same,
+    and their corresponding elements are equal. Note a "bytes" field,
+    although represented by []byte, is not a repeated field and the
+    rule for the scalar fields described above applies.
+  - Two unset fields are equal.
+  - Two unknown field sets are equal if their current
+    encoded state is equal.
+  - Two extension sets are equal iff they have corresponding
+    elements that are pairwise equal.
+  - Two map fields are equal iff their lengths are the same,
+    and they contain the same set of elements. Zero-length map
+    fields are equal.

+Package proto converts data structures to and from the wire format of
+protocol buffers.  It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+  - Names are turned from camel_case to CamelCase for export.
+  - There are no methods on v to set fields; just treat
+	them as structure fields.
+  - There are getters that return a field's value if set,
+	and return the field's default value if unset.
+	The getters work even if the receiver is a nil message.
+  - The zero value for a struct is its correct initialization state.
+	All desired fields must be set before marshaling.
+  - A Reset() method will restore a protobuf struct to its zero state.
+  - Non-repeated fields are pointers to the values; nil means unset.
+	That is, optional or required field int32 f becomes F *int32.
+  - Repeated fields are slices.
+  - Helper functions are available to aid the setting of fields.
+	msg.Foo = proto.String("hello") // set field
+  - Constants are defined to hold the default values of all fields that
+	have them.  They have the form Default_StructName_FieldName.
+	Because the getter methods handle defaulted values,
+	direct use of these constants should be rare.
+  - Enums are given type names and maps from names to values.
+	Enum values are prefixed by the enclosing message's name, or by the
+	enum's type name if it is a top-level enum. Enum types have a String
+	method, and a Enum method to assist in message construction.
+  - Nested messages, groups and enums have type names prefixed with the name of
+	the surrounding message type.
+  - Extensions are given descriptor names that start with E_,
+	followed by an underscore-delimited list of the nested messages
+	that contain it (if any) followed by the CamelCased name of the
+	extension field itself.  HasExtension, ClearExtension, GetExtension
+	and SetExtension are functions for manipulating extensions.
+  - Oneof field sets are given a single field in their message,
+	with distinguished wrapper types for each possible field value.
+  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+  - Non-repeated fields of non-message type are values instead of pointers.
+  - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+	package example;
+
+	enum FOO { X = 17; }
+
+	message Test {
+	  required string label = 1;
+	  optional int32 type = 2 [default=77];

+Package github provides a client for using the GitHub API.
+
+Usage:
+
+	import "github.com/google/go-github/v29/github"	// with go modules enabled (GO111MODULE=on or outside GOPATH)
+	import "github.com/google/go-github/github"     // with go modules disabled
+
+Construct a new GitHub client, then use the various services on the client to
+access different parts of the GitHub API. For example:
+
+	client := github.NewClient(nil)
+
+	// list all organizations for user "willnorris"
+	orgs, _, err := client.Organizations.List(ctx, "willnorris", nil)
+
+Some API methods have optional parameters that can be passed. For example:
+
+	client := github.NewClient(nil)
+
+	// list public repositories for org "github"
+	opt := &github.RepositoryListByOrgOptions{Type: "public"}
+	repos, _, err := client.Repositories.ListByOrg(ctx, "github", opt)
+
+The services of a client divide the API into logical chunks and correspond to
+the structure of the GitHub API documentation at
+https://developer.github.com/v3/.
+
+NOTE: Using the https://godoc.org/context package, one can easily
+pass cancelation signals and deadlines to various services of the client for
+handling a request. In case there is no context available, then context.Background()
+can be used as a starting point.
+
+For more sample code snippets, head over to the https://github.com/google/go-github/tree/master/example directory.
+
+Authentication
+
+The go-github library does not directly handle authentication. Instead, when
+creating a new client, pass an http.Client that can handle authentication for
+you. The easiest and recommended way to do this is using the golang.org/x/oauth2
+library, but you can always use any other library that provides an http.Client.
+If you have an OAuth2 access token (for example, a personal API token), you can
+use it with the oauth2 library using:
+
+	import "golang.org/x/oauth2"
+
+	func main() {
+		ctx := context.Background()
+		ts := oauth2.StaticTokenSource(
+			&oauth2.Token{AccessToken: "... your access token ..."},
+		)
+		tc := oauth2.NewClient(ctx, ts)
+
+		client := github.NewClient(tc)
+
+		// list all repositories for the authenticated user
+		repos, _, err := client.Repositories.List(ctx, "", nil)
+	}
+
+Note that when using an authenticated Client, all calls made by the client will
+include the specified OAuth token. Therefore, authenticated clients should
+almost never be shared between different users.
+
+See the oauth2 docs for complete instructions on using that library.
+
+For API methods that require HTTP Basic Authentication, use the
+BasicAuthTransport.
+
+GitHub Apps authentication can be provided by the
+https://github.com/bradleyfalzon/ghinstallation package.
+
+	import "github.com/bradleyfalzon/ghinstallation"
+
+	func main() {
+		// Wrap the shared transport for use with the integration ID 1 authenticating with installation ID 99.
+		itr, err := ghinstallation.NewKeyFromFile(http.DefaultTransport, 1, 99, "2016-10-19.private-key.pem")
+		if err != nil {
+			// Handle error.
+		}
+
+		// Use installation transport with client
+		client := github.NewClient(&http.Client{Transport: itr})
+
+		// Use client...
+	}
+
+Rate Limiting
+
+GitHub imposes a rate limit on all API clients. Unauthenticated clients are
+limited to 60 requests per hour, while authenticated clients can make up to
+5,000 requests per hour. The Search API has a custom rate limit. Unauthenticated
+clients are limited to 10 requests per minute, while authenticated clients
+can make up to 30 requests per minute. To receive the higher rate limit when
+making calls that are not issued on behalf of a user,
+use UnauthenticatedRateLimitedTransport.
+
+The returned Response.Rate value contains the rate limit information
+from the most recent API call. If a recent enough response isn't
+available, you can use RateLimits to fetch the most up-to-date rate
+limit data for the client.
+
+To detect an API rate limit error, you can check if its type is *github.RateLimitError:
+
+	repos, _, err := client.Repositories.List(ctx, "", nil)
+	if _, ok := err.(*github.RateLimitError); ok {
+		log.Println("hit rate limit")
+	}
+
+Learn more about GitHub rate limiting at
+https://developer.github.com/v3/#rate-limiting.
+
+Accepted Status
+
+Some endpoints may return a 202 Accepted status code, meaning that the
+information required is not yet ready and was scheduled to be gathered on
+the GitHub side. Methods known to behave like this are documented specifying
+this behavior.
+
+To detect this condition of error, you can check if its type is
+*github.AcceptedError:
+
+	stats, _, err := client.Repositories.ListContributorsStats(ctx, org, repo)
+	if _, ok := err.(*github.AcceptedError); ok {
+		log.Println("scheduled on GitHub side")
+	}
+
+Conditional Requests
+
+The GitHub API has good support for conditional requests which will help
+prevent you from burning through your rate limit, as well as help speed up your
+application. go-github does not handle conditional requests directly, but is
+instead designed to work with a caching http.Transport. We recommend using
+https://github.com/gregjones/httpcache for that.
+
+Learn more about GitHub conditional requests at
+https://developer.github.com/v3/#conditional-requests.
+
+Creating and Updating Resources
+
+All structs for GitHub resources use pointer values for all non-repeated fields.
+This allows distinguishing between unset fields and those set to a zero-value.
+Helper functions have been provided to easily create these pointers for string,
+bool, and int values. For example:
+
+	// create a new private repository named "foo"
+	repo := &github.Repository{
+		Name:    github.String("foo"),
+		Private: github.Bool(true),
+	}
+	client.Repositories.Create(ctx, "", repo)
+
+Users who have worked with protocol buffers should find this pattern familiar.
+
+Pagination
+
+All requests for resource collections (repos, pull requests, issues, etc.)
+support pagination. Pagination options are described in the
+github.ListOptions struct and passed to the list methods directly or as an
+embedded type of a more specific list options struct (for example
+github.PullRequestListOptions). Pages information is available via the
+github.Response struct.
+
+	client := github.NewClient(nil)
+
+	opt := &github.RepositoryListByOrgOptions{
+		ListOptions: github.ListOptions{PerPage: 10},
+	}
+	// get all pages of results
+	var allRepos []*github.Repository
+	for {
+		repos, resp, err := client.Repositories.ListByOrg(ctx, "github", opt)
+		if err != nil {
+			return err
+		}
+		allRepos = append(allRepos, repos...)
+		if resp.NextPage == 0 {
+			break
+		}
+		opt.Page = resp.NextPage
+	}
