[Docs] Documentation Improvements and Maintenance

[bbedward]

DMS has pretty extensive documentation, but there are gaps and it's difficult to single handedly cover everything accurately without a group effort.

So this is a meta, pinned help-wanted issue for documentation contributors.

For example, fixing typos, keeping it up to date, adding examples for mangowc or labwc or sway, etc.

To contribute to documentation:

1. Fork the repository: https://github.com/AvengeMedia/DankLinux-Docs
2. Make your enrichments
3. Open a pull request
