🎩 User Story

The developer should have a README explaining every engine.

📋 Related documentation

The only one that has some docs is decidim-api: https://github.com/AjuntamentdeBarcelona/decidim/tree/master/decidim-api

🎯 Acceptance criteria

When I go to any engine I should not see the boilerplate text ("Short description and motivation.")
