1. Find a Task: Look at the project's GitHub Issues. Pick one labeled good first issue or help wanted.

2. Follow the Rules:

Code: Follow the Dart/Flutter style guide. Use camelCase for variables, PascalCase for classes. Always run flutter format . before committing.

Docs: Write clearly and use Markdown.

UX: Use the Design System (check the /design folder for colors, fonts, and Figma files). Don't change the UI without discussing it first.

3. Test Your Work: Make sure your changes don't break anything. Write tests if you can.

4. Submit a Pull Request (PR):

Create a new branch for your work.

Fill out the PR Checklist in the template.

Clearly link your PR to the issue it fixes.

5. Report Bugs Well: When creating an issue, include details like your device, OS version, and steps to reproduce the problem.

In short: Communicate first, follow the established style, test your code, and submit a clean PR.
