Wrote a paragraph or two about verifying the QubesOS ISO signature and wrote a disclaimer that Qubes does not automatically verify external downloads not coming from its own repositories.
A few content changes, read over them to see if you like them:
* A few sentences were reworded so that end users could understand them better, without sacrificing detail.
* Sometimes more detail was added to give context to sentences or to make them more accurate.
* New sentences were added to help transitions in thought.
* New sentences were added to provide reasoning to earlier instructions so that the reader knew why they were important.
None of these content changes were particularly extensive or clashed with the original paper but they do change the meaning a bit, so I thought it important to document them.
Other changes:
* Subject-verb agreement
* Corrected some parentheses placements
* Misc. Grammar Fixes
* Inserted forgotten commas and periods
* Word variation
* Rework on some sentences that had really roundabout ways of saying things
In addition to my PR being a big edit, it is also on an important document. I have looked over my changes well and I know you will too. Reply if anything needs fixing/changing in the PR.
I have more changes that I want to add, but I figured I had edited the document enough already and if I added anythign else or made more extensive modifications it might be hard to tell what exactly I did.
This commit creates a single, central page (/doc/usb/) for all
USB-related information by combining stick-mounting.md with the
manual USB qube (formerly known as "USBVM") creation procedure
from security-guidelines.md. It rewrites the content from both of
those and adds the content requested in QubesOS/qubes-issues#1690.
It also redirects /doc/usbvm/ away from the ancient page on PVUSB.
