Linux has a manual, it's just hard to access. The usual procedure is:
* Open your preferred fedi client
* Tag a random selection of users @fosstodon.org
* Say "Linux sucks because I can't even _"
* Within seconds you will receive detailed and comprehensive instructions.
(nb: instructions might involve replacing your current Linux distro with one preferred by the user you tagged. simply retry, tagging other users, if this is the case.)
