Adapt documentation from Incognito
Originally created by Tails on #5977 (Redmine)
The Incognito’s documentation has been imported.
Left to do:
- see the comments on #6868 (closed) for a list of things that were inherited from Incognito’s documentation
- we’ve moved autorun in Windows (#6083 (closed)) to the wishlist, so tails within windows should be dropped.
Off-topic here:
- thunderbird: now tracked on children ticket from Return of Icedove? (#7158 (closed))
