@AnaSasso Thanks for updating this. A few comments:

It would be better to use a screenshot showing the entire page and then highlight the Catalog menu item. This screenshot would be hard for users to understand without context.

Same here, a full size screenshot would be better. Also, a larger image size as shown in the docs page would be nice.

This hyperlink points to the wrong "Filters" page as that refers to filtering user datasets. This should instead point to the ../map/filter page.

Also, could we add this as the last step of the usage guide rather than a note? As we would want users to always filter the data.

Lastly, I think the page might be easier to understand if the "Explore the GOAT data catalog" section is at the top and the "Use catalog data in your GOAT project" section is below it. Could we swap the ordering of the two?

I couldnt add a url to the stepper, so I added a 4th step but kept the hint
