 My knowledge base for misc. linux desktop and server setups/configurations
+This is a collaborative effort of Till Dieminger and me as our needs are similar enough to warrant a shared knowledge base.
 
-For dekstop environments a heavy Arch bias is to be expected but a lot of stuff can be applied in many distros. Switching out pacman/paru for the appropriate package manager of your choice will have to be done of course.

+For server stuff I have been mostly using Debian. Newer additions will assume Arch Linux on your server.
+This is because of Debian's ancient versions of software (python 3.7 is over 5 years old now) and the resultant overuse of docker or installing everything from source.
+If I `git clone` all my software why do I even need a package manager?
+To struggle with stupidly outdated versions of `python` and `nodejs`? No thanks.

+Newer additions will assume Arch Linux on your server.
+Most should be compatible with Debian as well though as Arch oftentimes just ships more minimalistic configs.
+Assuming of course that the two distros versions are comptatible.

 ### Goal
 
 - Set up a own caldav server which allows to sync [calcurse](https://www.calcurse.org/) with your other devices.
+If you want to run nextcloud anyways, you can also use its caldav server.
+This is a more light weight solution, which does not require a full php environment.
