 `/output` is the directory where the Docker container will export the files to.
-The `BASEURL` is the base of all urls. Per default it is [https://cp-algorithms.com](https://cp-algorithms.com).
+The `BASEURL` is the base of all urls.
+If you want to test it locally, e.g. you can set it `BASEURL=$PWD/public`, if you want to test it with Firebase (`firebase emulators:start`), use `BASEURL="http://localhost:5000"`, or if you want to deploy it to [https://cp-algorithms.com](https://cp-algorithms.com), use `BASEURL="https://cp-algorithms.com"`.
