You know what's super-awesome for writing prose documentation?

• Using inotify-tools ("inotify-tools" in Debian) so that when I save a source file in my editor, the HTML version is automatically rebuilt.
• Using livereload ("python3-livereload" in Debian) so that when the HTML version is built, it automatically reloads in my browser.

I'd previously experienced livereload as part of the mkdocs site-building tool, but I only recently discovered that it was a separate thing I could use anywhere. Definitely making more use of this in the future.
