Before following the bridge installation guide, you need to map apply a patch to bridges `portal.py`. Go to [portal.py](https://github.com/mautrix/signal/blob/master/mautrix_signal/portal.py) at [mautrix-signal](https://github.com/mautrix/signal) (don't forget to change to the correct commit/version of the file) and copy its content, create a `portal.py` on your host system and paste it in. Now you need to change two lines:
