+## Build
+
+The `cifplayer` is powered by `$mol`. Note that, unlike many other frontend frameworks, `$mol` provides the same single environment for all its projects, under the standard namespace scheme. That is, all your `$mol`-based code lives inside the same directory `$MOL_HOME`. So if you don't have `$MOL_HOME` yet, please create it and navigate there:
+
+```bash
+mkdir $MOL_HOME && cd $MOL_HOME
+```
+
+Then build with
+
+```bash
+npm exec mam optimade/tmdne/app
+```
+
+This will fetch the MAM server (MAM stands for the `$mol` abstract modules), clone this project, and compile it inside `optimade/tmdne/app/-/` subfolder. You will need the `web.js` bundle, that's it.
+
+
+## Develop
+
+Similarly to above, inside the `$MOL_HOME`, start the MAM dev-server with
+
+```bash
+npm exec mam
+```
+
+and navigate to http://localhost:9080, there select `optimade` namespace, then `tmdne`, then `app`. As you go through the folder structure, the selected project is being cloned and compiled on the fly, inside the corresponding subfolder of `$MOL_HOME`.
