Editing an existing topic or collection

I'm suggesting these edits to an existing topic or collection:

• Image (and my file is *.png, square, dimensions 288x288, size <= 75 kB)
• Content (and my changes are in index.md)

The project I am adding is very relevant in Brazil (and internationally recognized). It has an active community and maintainers.
