Contributor guide

Research direction
Check how to pass variables to Jinja templates in Eel. In Eel, you can use the `eel.start()` function with the `jinja templates` parameter and pass context via the template rendering. For example, you can modify your Python code to include `b` in the template context by using `eel.start(..., jinja templates='templates', context={'b': b})` or similar depending on Eel's API. Look at Eel documentation or examples for passing variables to Jinja templates.
