+### Build Quest Images
+
+In each quest folder, there is a `game.yml` file, which is the quest definition. And a optional `Dockerfile` to overwrite the base image. If you want to include additional files, put them in a `home` folder. The files in `home` will **not** be copied to the image automatically, you have to copy them in the `Dockerfile`.

+To build all quests:
+
+    yarn build:quests
+
+The base image is built with docker-compose, so you can use `docker compose build base` to rebuild it. Once you rebuild the base image, you have to rebuild all quests.
