+## Hydrogen support
+
+Thanks to [Aaron Raimist](https://github.com/aaronraimist), the playbook now supports [Hydrogen](https://github.com/vector-im/hydrogen-web) - a new lightweight matrix client with legacy and mobile browser support.
+
+By default, we still install Element, as Hydrogen is still not fully-featured. Still, people who'd like to try Hydrogen out can now install it via the plabook.
+
+Additional details are available in [Setting up Heisenbridge bouncer-style IRC bridging](docs/configuring-playbook-client-hydrogen.md).
