+### Telegram bridging
+
+> WIP
+
+Setting it up is a bit of a chicken/egg & chasing cats moment.
+
+You need to get your bot setup on the telegram side first and have these values:
+
+```
+api_id: ...
+api_hash: ...
+telegram_bot_token: ...
+```
+
+Here is a rough guide:
+
+```
+abra app secret insert <domain> telegram_api_hash v1 <secret>
+abra app secret insert <domain> telegram_bot_token v1 <secret>
+abra app secret generate -a <domain>
+
+abra app deploy <domain>
+abra app run matrix.fva.wtf telegram_bridge cat /data/registration.yaml
+abra app undeploy <domain>
+
+abra app secret rm <domain> telegram_as_token
+abra app secret insert <domain> telegram_as_token v1 <secret>
+
+abra app secret rm <domain> telegram_as_token
+abra app secret insert <domain> telegram_hs_token v1 <secret>
+
+abra app deploy <domain>
+```
+
+Some helpful documentation:
+
+- [`docs.mau.fi`](https://docs.mau.fi/bridges/python/setup/docker.html?bridge=telegram)
+- [`example-config.yaml`](https://mau.dev/mautrix/telegram/-/blob/master/mautrix_telegram/example-config.yaml)
+
+### 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
