I believe there should be a small section on what should be in the README.md of a repo (maybe add a template somewhere?), with at least the procedure to install, run and test the code. This should also be present in this repo's README. For example I had to :
pip3 install -r requirements.txt
pip3 install lark
Document the installation procedure: i.e. pip install ..
