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.
