+1. **Copy `.env.example` to `.env`**, change `APP_KEY` to a random 32 char string and set `APP_ENV` to `local`.
+2. Make sure **port 8080 is unused** *or else* change `DEV_PORT` to a free port on your host.
+3. **Run `chgrp -R docker storage`**. The development container will chown the `storage` directory to the `www-data` user inside the container so BookStack can write to it. You need to change the group to your host's `docker` group here to not lose access to the `storage` directory.
+4. **Run `docker-compose up`** and wait until the image is built and all database migrations have been done.
+5. You can now login with `
[email protected]` and `password` as password on `localhost:8080` (or another port if specified).
