+# garage1.yaml (Hörmann Garage Doors)
+This is the config for the Hörmann Garage Doors and it is absolutely snuffing stupid.
+
+First of all: It uses a ~~custom component~~... They are called external components now.
+Which starts the trouble. You currently cannot use it without using BOTH the door and the output since they are on the same file and I put no safeguards in yet. Maybe later.
+
+Second of all, if you want to change the door, just change the `garageSide` under `substitutions`. It's either `sy` or `wo`.
+Then let the custom components do their job I suppose. They are under [external_components/hoermann_door](external_components/hoermann_door). The [__init__.py](external_components/hoermann_door/__init__.py) needs to be there while the [cover.py](external_components/hoermann_door/cover.py) and [output.py](external_components/hoermann_door/output.py) make the platforms in `cover` and `output` available.
+
+Otherwise. they works but there is still room for improvements
