+### Discord bridging
+
+> WIP
+
+Just as messy as the Telegram bridging above! Rough guide:
+
+- get a local copy of [`config.yaml`](https://github.com/matrix-org/matrix-appservice-discord/blob/develop/config/config.sample.yaml)
+- fill it out with the values you need, all the discord token stuff, etc.
+- run `mkdir -p data && cp config.yaml data/` then `docker run --rm -v data:/data halfshot/matrix-appservice-discord:v1.0.0 sh -c "cd /data && node /build/src/discordas.js -r -u "http://discordbridge:9005" -c config.yaml"`
+- this generates the app service registration configuration you need to feed to the homeserver
+- run secret generation for the `discord_db_password`, insert your `discord_bot_token`
+- run `abra app cp <domain> discord-registration.yaml app:/discord-data` (it has to be called `discord-registration.yaml`)
+- deploy the bridge & happy hacking
