+
+A tool for bash writing bash completion in go.
+
+Writing bash completion scripts is a hard work. This package provides an easy way
+to create bash completion scripts for any command, and also an easy way to install/uninstall
+the completion of the command.
+
+## go command bash completion
+
+In [gocomplete](./gocomplete) there is an example for bash completion for the `go` command line.
+
+This is an example that uses the `complete` package on the `go` command - the `complete` package
+can also be used to implement any completions, see [Usage](#usage).
+
+### Install
+
+1. Type in your shell:
+```
+go get -u github.com/posener/complete/gocomplete
+gocomplete -install
+```
+
+2. Restart your shell
+
+Uninstall by `gocomplete -uninstall`
+
+### Features
+
+- Complete `go` command, including sub commands and all flags.
+- Complete packages names or `.go` files when necessary.
+- Complete test names after `-run` flag.
+
+## complete package
+
+Supported shells:
+
+- [x] bash
+- [x] zsh
+
+### Usage
+
+Assuming you have program called `run` and you want to have bash completion
+for it, meaning, if you type `run` then space, then press the `Tab` key,
+the shell will suggest relevant complete options.
+
+In that case, we will create a program called `runcomplete`, a go program,
+with a `func main()` and so, that will make the completion of the `run`
+program. Once the `runcomplete` will be in a binary form, we could 
+`runcomplete -install` and that will add to our shell all the bash completion
+options for `run`.
+
+So here it is:
+
+```go
+import "github.com/posener/complete"
+
+func main() {
+
+        // create a Command object, that represents the command we want
+        // to complete.
+        run := complete.Command{
+
+                // Sub defines a list of sub commands of the program,
+                // this is recursive, since every command is of type command also.
+                Sub: complete.Commands{
+
+                        // add a build sub command
+                        "build": complete.Command {
+
+                                // define flags of the build sub command
+                                Flags: complete.Flags{
+                                        // build sub command has a flag '-cpus', which
+                                        // expects number of cpus after it. in that case
+                                        // anything could complete this flag.
+                                        "-cpus": complete.PredictAnything,
+                                },
+                        },
+                },
+
+                // define flags of the 'run' main command
+                Flags: complete.Flags{
+                        // a flag -o, which expects a file ending with .out after
+                        // it, the tab completion will auto complete for files matching
+                        // the given pattern.
+                        "-o": complete.PredictFiles("*.out"),
+                },
+
+                // define global flags of the 'run' main command
+                // those will show up also when a sub command was entered in the
+                // command line
+                GlobalFlags: complete.Flags{
+
+                        // a flag '-h' which does not expects anything after it
+                        "-h": complete.PredictNothing,
+                },
+        }
+
+        // run the command completion, as part of the main() function.
+        // this triggers the autocompletion when needed.
+        // name must be exactly as the binary that we want to complete.
+        complete.New("run", run).Run()
+}
+```
+
+### Self completing program
+
+In case that the program that we want to complete is written in go we
+can make it self completing.
+
+Here is an [example](./example/self/main.go)
