 Add ability to force use of the development versions of `react` and `react-dom`
-by setting the `FORCE_REACT_DEVELOPMENT` environment variable to `true` when
-building, for example by using a command like `FORCE_REACT_DEVELOPMENT=true yarn
-build:all`.
+to allow for detailed error messages and use of fast-refresh. Note that builds
+with the development versions of `react` and `react-dom` should not be
+deployed in production.
+
+This feature can be used by setting the `FORCE_REACT_DEVELOPMENT` environment
+variable to `true`:
+
+```bash
+EXPERIMENTAL_MODULE_FEDERATION=true \
+FORCE_REACT_DEVELOPMENT=true \
+yarn build:all
+```
