Done!

@moufmouf Thanks, but it's still not triggered, maybe it would only pick up the yaml when it lands in master. Idea?

[moufmouf]

Indeed! The YAML needs to be on master to enable Github Actions. Let's merge this and see how it goes :D

Ok, we have the first batch of errors and Github Actions is enabled: https://github.com/thecodingmachine/graphqlite-bundle/actions/runs/956607478
