thanks! but this file is generated, you should add to docs/data/projects.yml

Thanks @joerick, I reverted my change and put it into docs/data/projects.yml

The docs will get regenerated on the next (weekly) update after merging.

PS: I'm also probably going to add a schema check for docs/data/projects.yml soon, which will make these PRs get checked even before the docs run.
