     Material for MkDocs only bundles selected plugins in order to keep the size
     of the official image small. If the plugin you want to use is not included,
-    create a `user-requirements.txt` file in the repository root with the packages
+    you can add them easily:
-    you want to install additionally, e.g.:
 
-    ``` txt title="user-requirements.txt"

+        RUN pip install mkdocs-macros-plugin
+        RUN pip install mkdocs-glightbox
         ```

+
+        Clone or fork the Insiders repository, and create a file called
+        `user-requirements.txt` in the root of the repository. Then, add the
+        plugins that should be installed to the file, e.g.:
+
+        ``` txt title="user-requirements.txt"
+        mkdocs-macros-plugin
+        mkdocs-glightbox
