Overhaul end user documentation
Heavily WIP. This MR contains the first changes to end user documentation. The focus here is on a few main things:
- Create shorter, more specific content.
- Make the language easier to read and understand.
- Maintain a consistent style.
- Cover more end-user tasks.
- Use Markdown rather than RST.
There is a lot to do here, so I'm just opening this for now to prompt me to keep plugging away at it.
-
Recreate all existing content in new style. -
Add missing content. -
Add mobile UI documentation. -
Remove existing content. -
Create coherent layout for all pages. -
Set up redirects.
