<EDIT>Welcome! If you inform yourself about GNU/Linux, e.g. in the wiki, and find outdated, further, new entries you can report it immediately, you are invited to contribute.</EDIT>
Since I often read that the information from https://wiki.linuxaudio.org is (partly) outdated, my suggestion is:
Collect the obsolete entries here with the current correct correction worked out in community.
We can then add them to the wiki, i.e. bring the wiki up to date.
In my opinion this would help everyone.
