+# Generating Man Pages For Your Own cobra.Command
+
+Generating man pages from a cobra command is incredibly easy. An example is as follows:
+
+```go
+package main
+
+import (
+	"log"
+
+	"github.com/spf13/cobra"
+	"github.com/spf13/cobra/doc"
+)
+
+func main() {
+	cmd := &cobra.Command{
+		Use:   "test",
+		Short: "my test program",
+	}
+	header := &doc.GenManHeader{
+		Title: "MINE",
+		Section: "3",
+	}
+	err := doc.GenManTree(cmd, header, "/tmp")
+	if err != nil {
+		log.Fatal(err)
+	}
+}
+```
+
+That will get you a man page `/tmp/test.3`
