+
+## How to Contribute
+
+### 1. Reporting Issues
+
+* Use the **[GitHub Issues tab](../../issues)** to report bugs, request features, or ask questions.
+* Please search existing issues before opening a new one to avoid duplicates.
+
+### 2. Suggesting Improvements
+
+* If you have ideas or feedback, open an **issue** with the label `enhancement` or `discussion`.
+* Include as much context as possible to help others understand your suggestion.
+
+### 3. Submitting Code
+
+We follow the standard GitHub **fork-and-pull request workflow**:
+
+1. **Fork** the repository.
+2. **Create a branch** for your changes (`git checkout -b feature/your-feature-name`).
+3. **Make your changes** and commit them with clear messages.
+4. **Push** your branch to your fork.
+5. **Open a Pull Request (PR)** against the `main` branch.
+
+> Please keep PRs focused and small when possible. This makes reviewing easier and speeds up merging.
+
+### 4. Code Style
+
+* Follow existing project conventions (naming, formatting, folder structure).
+* If in doubt, match the style you see in the repo.
+
+### 5. Questions
+
+If you’re unsure about something, feel free to open an issue and start a discussion.
