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
As mentioned in #1071, this page is really about troubleshooting.
Reading this page normally shouldn't be required, so it doesn't
really belong under "Common Tasks."
The only exception to this would be non-Linux VMs for which a
manual sync is required. That's one argument in favor of moving
this under "Advanced Configuration" rather than "Troubleshooting,"
but at least half of this page is undeniably about troubleshooting.
There's also a "behind the scenes" section at the end that belongs
in the Developer Documentation.
