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

Please replace this line with an explanation of your proposed changes.

Hi, thank you for reviewing my pull request! I mistakenly checked the box stating that I am not the sole author of the topic I’m modifying. However, I am the sole author of the changes made in this pull request, and I’ve contributed them independently.

Please let me know if there’s anything else I need to clarify or update to help move this forward. Thank you for your time and assistance!

@rendred Thank you for your contribution. Unfortunately, this isn't quite ready and cannot be included as-is.

While there are 1.5M repos already tagged with this topic, this topic is about a concept, not a particular piece of technology or product. Therefore, there should be no logo or url included. The wikipedia url should be included under the wikipedia_url field.
