+# Contributing from a Fork
+
+Thank you for contributing to Roo Code! If you're contributing from a forked repository, please be aware of the following regarding CI workflows.
+
+## Integration Tests for Fork PRs
+
+**Important**: Integration tests (E2E tests) will be **skipped automatically** for pull requests from forked repositories.
+
+### Why Are Tests Skipped?
+
+For security reasons, GitHub does not expose repository secrets (like API keys) to workflows triggered by pull requests from forks. This is a critical security feature that prevents malicious actors from:
+
+- Stealing API keys
+- Running up costs on paid API services
+- Accessing sensitive infrastructure
+
+Since our integration tests require an OpenRouter API key (`OPENROUTER_API_KEY` secret) to test real AI interactions, they cannot run on fork PRs without this secret.
+
+### What This Means for Your PR
+
+1. **Your PR will show integration tests as "skipped"** - this is expected and normal
+2. **Other CI checks will still run** - linting, type checking, unit tests, etc.
+3. **A maintainer will review your PR** - after code review, maintainers can:
+    - Trigger integration tests manually
+    - Merge your PR to a branch in the main repo where tests can run
+    - Run tests locally before merging
+
+### What You Should Do
+
+1. **Ensure all other CI checks pass** - unit tests, linting, type checking
+2. **Test your changes locally** if possible:
+    - Follow the E2E testing guide in [`apps/vscode-e2e/README.md`](../apps/vscode-e2e/README.md)
+    - Set up your own OpenRouter API key for local testing
+3. **Provide clear testing evidence** in your PR description:
+    - Screenshots or videos of functionality working
+    - Description of manual testing performed
+    - Any relevant logs or output
+4. **Be patient** - maintainers will run full integration tests during review
+
+### Running Integration Tests Locally
+
+If you want to run integration tests locally before submitting your PR:
+
+1. **Get an OpenRouter API key**:
+
+    - Sign up at [OpenRouter](https://openrouter.ai/)
+    - Add credits to your account (tests cost ~$0.10-0.50 to run)
+
+2. **Set up local environment**:
+
+    ```bash
+    cd apps/vscode-e2e
+    cp .env.local.sample .env.local
+    # Edit .env.local and add your OPENROUTER_API_KEY
+    ```
+
+3. **Run the tests**:
+    ```bash
+    pnpm test:ci
+    ```
+
+See the [E2E Testing README](../apps/vscode-e2e/README.md) for complete instructions.
+
+### Alternative: Request Maintainer Testing
+
+If you cannot run integration tests locally, you can:
+
+1. Submit your PR with all other CI checks passing
+2. Add a comment requesting integration test runs
+3. A maintainer will review your code and run integration tests
+
+## Other CI Workflows
+
+The following workflows **will run** on fork PRs:
+
+- ✅ **Linting** - Code style and quality checks
+- ✅ **Type checking** - TypeScript type validation
+- ✅ **Unit tests** - Fast, isolated tests without external dependencies
+- ✅ **Translation checks** - Ensuring all translations are complete
+- ✅ **Dependency checks** (Knip) - Unused dependency detection
+
+These workflows provide significant code quality assurance even without integration tests.
+
+## Questions?
+
+If you have questions about fork contributions or testing:
+
+- Check the [main CONTRIBUTING guide](../../CONTRIBUTING.md)
+- Ask in the PR discussion
+- Reach out in the community channels
+
+Thank you for contributing to Roo Code!

+### Fork Pull Requests
+
+**Important**: Integration tests are **automatically skipped** for pull requests from forked repositories.
+
+This is a security requirement - GitHub does not expose repository secrets to fork PRs to prevent unauthorized access to API keys and other sensitive credentials. Since these tests require the `OPENROUTER_API_KEY` secret, they cannot run on fork PRs.
+
+**For fork contributors**: See [`.github/FORK_CONTRIBUTORS.md`](../../.github/FORK_CONTRIBUTORS.md) for:
+
+- Why tests are skipped on fork PRs
+- How to run tests locally with your own API key
+- What maintainers will do to test your PR
+
+**For maintainers**: After reviewing a fork PR's code, you can:
+
+- Manually trigger the workflow with repository secrets
+- Merge the PR to a branch in the main repo where tests will run automatically
+- Run tests locally before merging
