 2. You can run tests by running `pytest` in the root, or by running `python3 setup.py test`. Code coverage is enabled with pytest-cov.
 3. Edit the `setup.py` of your project to make it truly yours. Remove my email and info from here and put your own info. You may as well delete the full `setup.py` file instead of adapting it if you don't intend to publish your project on `pip` nor on `conda` as  a package. 
 4. Start coding in your now-renamed project folder and add some more tests under the `testing/` folder!

 ## Understanding how this template works
 
-The article [The optimal python project structure](https://awaywithideas.com/the-optimal-python-project-structure/?ref=gucci_neuraxio) by Luke Tonin does a good job at explaining how a template like the present one works. The present template is a bit more complete and complex than in the article, thought, as it already includes a test suite (including a starter test example), and a thorough `setup.py` file for your project to be properly packaged.

+There is also my [video on software architecture](https://youtu.be/K4QN27IKr0g?t=1211) that can help, in which I do the overview of a full project based on this template, in terms of theoretical software architecture rather than practical how-to use the template.
