Hi @solegalli, thanks so much for proposing your project for the sprints!

I noticed the build is currently failing with this message:

[ERROR] Error: No headlines allowed in description. [feature-engine-sprint-proposal]

To fix this, you can just swap out the Markdown headings (#, ##, etc.) for bold text (**) or numbered/bullet-point lists.

While you're making that tweak, could you also condense the description a bit? We encourage shorter descriptions so it's fair to all projects and easier for attendees to scan through their options. For a good sense of the target length, feel free to check out last year's sprint projects.

Thanks!

@solegalli in case you want to keep your extended description, my suggestion is that you add an “EuroPython sprints” meta issue to the repo associated with your project and then you link to it from the short/scanneable description you add to the EP website.
