Not a Wiki--there's no Edit button. It would be great to actually make it a wiki (and have changes recorded in git). From the Github readme: > Crontributing > Missing entry? Found a typo? Please don't hesitate to create an issue or submit a pull request. > Edit on GitHub > The content is located in src/articles. You can find the file and click the edit button (the pencil icon) in the top right corner to start editing…
Each page has a 'Edit on GitHub' button. You just need your changes to be approved, so I guess it's like a moderated wiki.
The [Edit on Github] button didn't go anywhere for me and I don't see how to create a new 'card'/entry. There seems to be (IMO) too much friction for this to be well-maintained.
