-install pip to get the newest versions.
+The Python tools should always be run with the most recent version.
+In particular, pylint tends to have a lot of breaking changes between versions.
+The easiest way, to handle these Python dependencies is to run your
+development from within a virtual environment.

+### Running Nominatim during development

+The source code for Nominatim can be found in the `src` directory and can
+be run in-place. The source directory features a special script
+`nominatim-cli.py` which does the same as the installed 'nominatim' binary
+but executes against the code in the source tree. For example:
