Editing an existing topic or collection

I'm suggesting these edits to an existing topic or collection:

• Image (and my file is *.png, square, dimensions 288x288, size <= 75 kB)
• Content (and my changes are in index.md)

Please replace this line with an explanation of why you think these changes should be made.

Curating a new topic or collection

• I've formatted my changes as a new folder directory, named for the topic or collection as it appears in the URL on GitHub (e.g. https://github.com/topics/[NAME] or https://github.com/collections/[NAME])
• My folder contains a *.png image (if applicable) and index.md
• All required fields in my index.md conform to the Style Guide and API docs: https://github.com/github/explore/tree/main/docs

Please replace this line with an explanation of why you think this topic or collection should be curated.

Something that does not neatly fit into the binary options above

• My suggested edits are not about an existing topic or collection, or at least not a single one
• My suggested edits are not about curating a new topic or collection, or at least not a single one
• My suggested edits conform to the Style Guide and API docs: https://github.com/github/explore/tree/main/docs

Added the Art topic to make it easier for users to discover and understand art-related projects by providing a clear description, related topics, and useful metadata.

Subject/Message: Quick fix needed on the "Art" topic!

Hi! abdirahmanafjar The automated tests caught one small error in your commit for the art topic.

The Error: In the topics/art/index.md file, art is included in the list of related: topics. GitHub doesn't allow a topic to be related to itself.

How to Fix it: All you need to do is open that file and remove art, from the related list. The related list should just start with design instead.

Let me know once you've updated the file and pushed the new commit!
