+### [How do you add client configurations?
+If the environment variable `PEERS` is set to a number, the container will run in server mode and the necessary server and peer/client confs will be generated. The peer/client config qr codes will be output in the docker log. They will also be saved in text and png format under /config/peerX.
+
+Variables `SERVERURL`, `SERVERPORT`, `INTERNAL_SUBNET` and `PEERDNS` are optional variables used for server mode. Any changes to these environment variables will trigger regeneration of server and peer confs. Peer/client confs will be recreated with existing private/public keys. Delete the peer folders for the keys to be recreated along with the confs.
+
+To add more peers/clients later on, you increment the `PEERS` environment variable and recreate the container.
+
+To display the QR codes of active peers again, you can use the following command and list the peer numbers as arguments: `docker-compose exec -it wireguard /app/show-peer 1 4 5` will show peers #1 #4 and #5 (Keep in mind that the QR codes are also stored as PNGs in the config folder).
+
+The templates used for server and peer confs are saved under /config/templates. Advanced users can modify these templates and force conf generation by deleting /config/wg0.conf and restarting the container.
