**Note**: bridging to [IRC](https://en.wikipedia.org/wiki/Internet_Relay_Chat) can also happen via the [matrix-appservice-irc](configuring-playbook-bridge-appservice-irc.md) bridge supported by the playbook.
The playbook can install and configure [Heisenbridge](https://github.com/hifi/heisenbridge) - the bouncer-style [IRC](https://en.wikipedia.org/wiki/Internet_Relay_Chat) bridge for you.
See the project's [README](https://github.com/hifi/heisenbridge/blob/master/README.md) to learn what it does and why it might be useful to you. You can also take a look at [this demonstration video](https://www.youtube.com/watch?v=nQk1Bp4tk4I).
Below are the common configuration options that you may want to set, exhaustive list is in [the bridge's defaults var file](../roles/custom/matrix-bridge-heisenbridge/defaults/main.yml).
