-# Crystal Linux Contributing Guidelines
-
-#### !! Always make sure to `git pull` before doing any work to avoid commit hell !!
-
-### Pre-Commit Checks
-
-- Make sure to `cargo fmt` your code before every commit push
-- Unless in specific edge cases, don't push code that doesn't pass `cargo check`
-- Try to correct any code with `cargo clippy` before you push
-
-### Formatting
-
-- UNIX line endings (LF instead of CRLF)
-- 4 spaces per TAB
-
-### Good Practices
-
-- Try to use .unwrap() as little as possible
-- Try to never use panic!() in production code, always try to have a possible way to resolve errors, even if it's just
-  unwrap_or/_else()
-- Never use println!() or eprintln!() in finalised code. Using string functions (e.g. info() in Amethyst v3.0.0) is
-  preferred
-- Compartmentalise as much as you can, avoid writing the exact same line of code 50 times if you can turn it into a
-  function
-
-### Examples of these guidelines in practice
