+#### Making an edit
+
+Edit the `.md` files in your preferred editor. They are written in markdown,
+which comes in different flavors. You you can [get an intro to markdown
+here](https://www.markdownguide.org/) or read the syntax of the markdown flavor
+we use [here](https://kristaps.bsd.lv/lowdown/lowdown.5.html).

+message. Write a short summary of the changes you made.

+Push your changes:
+
+```
+git push origin master
+```
