-#### LSP servers
-
-Scripts are supplied in `scripts/` for each server I use. Run these for the
-corresponding server that you would like to be installed.
-
-The process in no way is automated or "purely in lua or vimscript", but it more
-just holds your hand a bit. There may be plans in the future to automate this
-with our own package manager. But I might start writing my own editor by that
-point. So we'll see.
-
-If you'd like to add a new LSP server, feel free. Just make sure to ask the
-user if all dependencies are installed. Currently, this is achieved using
-`query_dep` in `query_dependency.sh`. All it does is ask the user if the
-dependency is installed and quits the install script if any dependency is not
-installed. *(don't even remind me how hacky that is)*
-
-However, a proper package management system would be more prefered. So never
-feel like this pattern is in any way enforced. I can't be biased toward which
-packages for which package managers will get maintained. And I can't be
-bothered to write a package for every package manager that ever exists. If it
-bothers you enough, change it to specifically work with your system. And maybe
-contribute so others maybe follow suit.
