-# threaded network chat refactor
-
-I have split functions semantically into different files and tied all global variables together in
-`public.h` so they work without modifications.
-
-Additional changes:
-- Fixed the dreaded bug where you have to launch the program twice to make it work
-- Adjusted the ncurses stuff a bit so it doesn't look as janky
-- Changed server/client mode (`mode` variable) from an integer to an enum (still works as an integer)
-
-## What now?
-
-See TODO. From here we're going to push the code to the gitlab like we were told to after everyone
-is set up. Follow the coding style guidelines because otherwise everything will be extremely gross
-and inconsistent. If you set up your editor correctly, it will take care of most of that stuff.
-
-## TODO
-
-- Finalize coding style,
-  - **see [STYLE.md](STYLE.md)**
-- Get everyone's editors set up for clangd/clang-format and git
-- Make sure everyone's compiler toolchains work
-- Decide who gets what responsibilities
-- Distribute appropriate code to people with those responsibilities
-- Have everyone upload their respective code to their sections of the gitlab
