+# Cobra Generator
+
+Cobra provides its own program that will create your application and add any
+commands you want. It's the easiest way to incorporate Cobra into your application.
+
+In order to use the cobra command, compile it using the following command:
+
+    go get github.com/spf13/cobra/cobra
+
+This will create the cobra executable under your `$GOPATH/bin` directory.
+
+### cobra init
+
+The `cobra init [app]` command will create your initial application code
+for you. It is a very powerful application that will populate your program with
+the right structure so you can immediately enjoy all the benefits of Cobra. It
+will also automatically apply the license you specify to your application.
+
+Cobra init is pretty smart. You can provide it a full path, or simply a path
+similar to what is expected in the import.
+
+```
+cobra init github.com/spf13/newApp
+```
+
+### cobra add
+
+Once an application is initialized, Cobra can create additional commands for you.
+Let's say you created an app and you wanted the following commands for it:
+
+* app serve
+* app config
+* app config create
+
+In your project directory (where your main.go file is) you would run the following:
+
+```
+cobra add serve
+cobra add config
+cobra add create -p 'configCmd'
+```
+
+*Note: Use camelCase (not snake_case/snake-case) for command names.
+Otherwise, you will encounter errors.
+For example, `cobra add add-user` is incorrect, but `cobra add addUser` is valid.*
+
+Once you have run these three commands you would have an app structure similar to
+the following:
+
+```
+  ▾ app/
+    ▾ cmd/
+        serve.go
+        config.go
+        create.go
+      main.go
+```
+
+At this point you can run `go run main.go` and it would run your app. `go run
+main.go serve`, `go run main.go config`, `go run main.go config create` along
+with `go run main.go help serve`, etc. would all work.
+
+Obviously you haven't added your own code to these yet. The commands are ready
+for you to give them their tasks. Have fun!
+
+### Configuring the cobra generator
+
+The Cobra generator will be easier to use if you provide a simple configuration
+file which will help you eliminate providing a bunch of repeated information in
+flags over and over.
+
+An example ~/.cobra.yaml file:
+
+```yaml
+author: Steve Francia <spf@spf13.com>
+license: MIT
+```
+
+You can specify no license by setting `license` to `none` or you can specify
+a custom license:
+
+```yaml
+license:
+  header: This file is part of {{ .appName }}.
+  text: |
+    {{ .copyright }}
+
+    This is my license. There are many like it, but this one is mine.
+    My license is my best friend. It is my life. I must master it as I must
+    master my life.
+```
+
+You can also use built-in licenses. For example, **GPLv2**, **GPLv3**, **LGPL**,
+**AGPL**, **MIT**, **2-Clause BSD** or **3-Clause BSD**.
