Hi @juliocmfj, Welcome to the Community!
If you missed my recent thread for new visitors, take a look at it below:
New Here? Read This! - General - Community | MonoGame
I placed the Discord link in there too.
You can find some helpful information in there, I should be adding to it regularly for a while.
And no, MonoGame is very much still going. What are you looking to achieve with MonoGame?
Happy Coding!
