Thanks for submitting this PR - the resources are great!

I would prefer that these resources go under a different section than 'getting started'. One option would be to have a new "Examples" section that could include the "Gallery" and "External examples". I think that the external tutorials could be included in that section for now, but long term could go into the redesigned tutorial sidebar (#1191).

Also, I prefer "External examples" or something else over "User Contributed Resources" to make it more clear PyGMT is not trying to take ownership of these resources and is just providing links. I think this could make people who aren't PyGMT developers more likely to include links to their PyGMT projects in the page.

I agree with @meghanrjones , would also use something like "External examples".

Good suggestion. I renamed the page to "External Resources" and moved it to the "Examples" section.

Looks good to me! I just have one small comment about the instructions for adding an example.
