Description

We have no instructions explaining how to add examples to the GMT gallery. PR #3296 is a good examples showing what files need to be added/updated.

We should document it in CONTRIBUTING.md or in the `doc/examples/README.examples` file. I prefer the latter.

This issue has not been assessed yet.
