How to contribute to a C project
Most projects use Make (`make`) or CMake. Read the build instructions carefully — flags and dependencies vary.
- Compile cleanly with the project's warning flags before submitting.
- Be careful with memory management; reviewers look closely at allocations.
- Documentation and portability fixes are good first contributions.
