# Generating Markdown Docs For Your Own cobra.Command # Generating Markdown Docs For Your Own cobra.Command
Generating man pages from a cobra command is incredibly easy. An example is as follows:
```go
package main
import (
"github.com/spf13/cobra"
"github.com/spf13/cobra/doc"
)
func main() {
cmd := &cobra.Command{
Use: "test",
Short: "my test program",
}
doc.GenMarkdownTree(cmd, "/tmp")
}
```
That will get you a Markdown document `/tmp/test.md`
