+Setup & debug
+=============
++ clone the repo and cd to the cloned dir
++ ``python3.11 -m venv .venv``
++ ``source .venv/bin/activate``
++ ``pip install build``
++ ``python -m build``
++ ``pip install -e .``
++ ``pip list`` (pip show abibas, pip uninstall abibas, etc)
+
+At this stage the package is installed in editable mode, to run it in debug mode:
+
++ ``abibas-debug``
+
+or in normal mode:
+
++ ``abibas``
+
+If in debug mode changes made to the Flask app will be applied automatically at runtime,
+for the changes in simulator though the tool has to be restarted.
+
+**main** module can be manipulated for debugging purposes as well
