 It handles client creation and removal, and will auto-generate the corresponding private and public keys. It can also generate the configuration file for each client.

+## Wireguard configuration file
+
+This software will parse and edit the Wireguard configuration file specified in `/etc/wgmgr.conf`. While several protections are in place, be advised that this software *might* permanently destroy your Wireguard configuration. Always have backups!
+
+Each new client is added to the configuration file with a `[Peer]` stanza like the following:
+
+```
+# The Peer Name
+[Peer]
+AllowedIPs = 10.8.0.2/32
+PublicKey = GSiujJjngvyLTR0/93l/EUGIs7ohDpKDhoa0WrEXJnA=
+```
+
+The corresponding private key will be stored in `/etc/wireguard/private_keys/The Peer Name`. Permissions should automatically be set to `rw-------` (600), preventing anyone but root from reading it.
