Ways to Participate in the Community

Beginner: Star + Watch

The simplest form of support. Starring helps a project gain more exposure.

Intermediate: File an Issue

When reporting a bug, provide: the environment, reproduction steps, and expected vs actual behavior
When filing a feature request, explain: the use case and why the existing functionality is not enough

Advanced: Submit a PR

# Standard Procedure
gh repo fork owner/repo
git clone https://github.com/your-username/repo.git
cd repo
git checkout -b fix/your-fix
# Make Changes
git commit -m "fix: description of fix"
git push origin fix/your-fix
gh pr create --base main --head your-username:fix/your-fix
