 ### Skill Levels
 
-If you aren't fluent in Rust:
+If you don't know programming:
 
 - Write documentation
 - Use and test Redox, fill issues for bugs or needed features (please verify the repository issues before)
+
+If you don't know how to code in Rust, but know in other programming languages:
+
 - Web development on the website (we don't accept JavaScript code)
 - Write unit tests (may require minimal knowledge of Rust)
+- Port programs to Redox
 
-If you are fluent in Rust, but not operating system Development:
+If you know how to code in Rust, but don't know operating system development:
 
-- Improve the Orbital display server and window manager.
-- Port programs written in Rust to Redox (in most cases you need to port crates, be aware of missing functions on relibc, porting without these functions will make patches dirty)
-- Improve the program compatibility in relibc
-- Improve the package manager
 - Improve the [Ion](https://gitlab.redox-os.org/redox-os/ion) shell
