+## Initialize
+
+The `homestar init` command generates a Homestar settings file and optionally key material. Use the `--key-seed` or `--key-file` options to use existing key material.
+
+Settings and key material are written to `~/.config/homestar` by default, but the output location can be overriden with the `--output` option.
