# GPG WKD setup > The source of the WKD at vhack.eu The directory structure follows the advanced way to implement the [WKD][1] specification. ## Current GPG-Keys: These are listed in [the keys file](./stored_keys.md). Use the [mk_key](./scripts/mk_key.sh) script to add a key (see it's help for options). ## Reference All directories must also server a `policy` file. This can however be zero size.
