- Warn against using direct commands (in part due to
QubesOS/qubes-issues#6275).
- Remove duplicate content from dom0 and domU pages. Link to main update
page instead.
- Add information on command-line equivalents to the Qubes Update tool,
since many Qubes users prefer to run updates via the command-line.
Those are fields used by the language switcher to correlate pages across
different languages, even if they have different names/paths/titles.
They are generated with the prepare_for_translation.py script.
- mark all code blocks with ```
- unify empty lines between sections
- adjust list syntax (no space before dash)
- adjust headers to use Atx-style syntax
- remove trailing spaces
