What about naming it like "general contribution workflow". Often projects place infos like that into the "contribution" guide.
I would also leave a link to the sandbox project, stating that further detailed explanations are present there, OR (what I really prefer) that we move/copy content of sandbox readme with pictures over here. Sandbox should be treated as playground and not the place with further documentation.
Definitely writing: "you can play around and test the process on the sanbox project" would make sense for me.

I´m not sure if there are more requested changes.

To this comment I can say: I agree with you but I´m not sure if I cloud do that alone. regardless of my ability to implement this request I would like to open a new commit+PR for this.
