 Documentation can be built from the [quickshell-docs](https://git.outfoxxed.me/outfoxxed/quickshell-docs) repo,
 though is currently pretty lacking.
 
+Some fully working examples can be found in the [quickshell-examples](https://git.outfoxxed.me/outfoxxed/quickshell-examples) 
+repo.
+
+Both the documentation and examples are included as submodules with revisions that work with the current
+version of quickshell.
+
+You can clone everything with
+```
+$ git clone --recursive https://git.outfoxxed.me/outfoxxed/quickshell.git
+```
+
+Or clone missing submodules later with
+```
+$ git submodule update --init --recursive
+```
