 ### Installing prerequisites on Ubuntu/Debian
 
-Some of the Python packages require the newest version which is not yet

-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:
+
+```
+me@machine:~$ cd Nomiantim
+me@machine:~Nomiantim$ ./nominatim-cli.py --version
+Nominatim version 4.4.99-1

 ## Executing Tests
 
 All tests are located in the `/test` directory.

 extend the test suite, see the [Testing chapter](Testing.md).
