 You should probably use a virtualenv for that.
 I develop `jon` using Python 3.10 but it should work with older versions as well.
 
+### Building Frontend JS
+
+Most of jon works without JS but there are some features that require it.
+The frontend code lives in `./frontend` and is written using Elm, a functional language that compiles to JS.
+To compile the Elm code to `.js` files, first make sure that the Elm compiler is installed:
+
+```
+elm --version
+# 0.19.1
+```
+
+Then run `make frontend`.
+
 ## Running
