Is your feature request related to a problem? Please describe.
As a visitor, I miss some relevant information in the participatory budget component landing page.

Describe the solution you’d like
I want to see some relevant information on this home page:

• Title
• Short description
• Calendar
• How to participate

Describe alternatives you’ve considered
In the future this could be solved using the content block layout system. But for the moment this is a specific need for the Barcelona instance to be solved with HTML and CSS.

Additional context

Does this issue could impact on users private data?
No, it's about the landing page design.
