+### Development
+
+To use latest up-to-date repositories alongside avalon-setup while developing, you can override the submodules used internally via environment variables.
+
+**avalon-local.bat**
+
+```bat
+@echo off
+
+set AVALON_CORE=<path/to/avalon-core>
+set AVALON_LAUNCHER=<path/to/avalon-launcher>
+set AVALON_PROJECTS=<path/to/avalon-examples>
+set AVALON_CONFIG=<my_config>
+set AVALON_LABEL=<my label>
+set AVALON_SENTRY=<replace me>
+set AVALON_MONGO=mongodb://<mongodb-address>
+
+set PYTHONPATH=<path/to/config>;%PYTHONPATH%
+
+python <path/to/avalon-setup>/avalon.py %*
+```
