+# Continuous Integration Setup
+
+This project uses Gitea Actions for continuous integration and testing.
+
+## Workflows
+
+### Main CI Workflow (`.gitea/workflows/ci.yml`)
+Runs on every push to `main` or `dev` branches and on pull requests.
+
+**Steps:**
+1. Checkout code with submodules
+2. Install system dependencies (CMake, GLM, OpenSSL, zlib, curl)
+3. Install Rust nightly toolchain
+4. Cache build artifacts
+5. Build Rust bridge
+6. Configure and build C++ project
+7. Run unit tests
+8. Check Rust code formatting
+9. Run Rust clippy for linting
+10. Upload build artifacts
+
+### Rust Quality Checks (`.gitea/workflows/rust-quality.yml`)
+Runs on changes to `bridge/**` directory.
+
+**Steps:**
+1. Format checking with `cargo fmt`
+2. Linting with `cargo clippy`
+3. Unused dependency detection with `cargo udeps`
+4. Security audit with `cargo audit`
+5. Documentation build verification
+
+## Local Testing
+
+You can run the full CI test suite locally:
+
+```bash
+./ci-test.sh
+```
+
+This script:
+- Cleans the build directory
+- Builds the Rust bridge
+- Builds the C++ project
+- Runs all tests
+- Performs code quality checks
+
+## Test Requirements
+
+### System Dependencies
+- Ubuntu 20.04+ or compatible Linux distribution
+- CMake 3.15+
+- GCC/Clang with C++20 support
+- Rust nightly toolchain
+
+### Runtime Dependencies
+- libglm-dev
+- libssl-dev
+- zlib1g-dev
+- libcurl4-openssl-dev
+
+## Current Test Coverage
+
+### C++ Tests (`tests/TestHarness.cpp`)
+1. **Protocol Signature Stability**: Verifies the Overte protocol version signature
+2. **Discovery JSON Parsing (Vircadia)**: Tests parsing domain list with Vircadia field names
+3. **Discovery JSON Parsing (Overte)**: Tests parsing domain list with Overte field names
+
+### Rust Bridge Tests
+Currently relies on successful compilation. Future additions:
+- Unit tests for C ABI functions
+- Integration tests with mock StardustXR server
+- Property propagation tests
+
+## CI Status Badge
+
+Add this to your Gitea repository README:
+
+```markdown
+[![CI](https://your-gitea-instance.com/username/starworld/actions/workflows/ci.yml/badge.svg)](https://your-gitea-instance.com/username/starworld/actions)
+```
+
+Replace `your-gitea-instance.com` and `username` with your actual values.
+
+## Debugging CI Failures
+
+### Build Failures
+Check the "Build C++ project" or "Build Rust bridge" step logs:
+- Ensure all dependencies are installed
+- Check for compilation errors
+- Verify submodules are initialized
+
+### Test Failures
+Check the "Run tests" step:
+- Review test output for specific failures
+- Tests validate protocol signatures - may need updating if Overte protocol changes
+- JSON parsing tests check both Vircadia and Overte field formats
+
+### Cache Issues
+If builds are slow or failing mysteriously:
+1. Clear GitHub Actions cache (Repository Settings → Actions → Caches)
+2. Re-run the workflow
+
+## Adding New Tests
+
+### C++ Tests
+Edit `tests/TestHarness.cpp`:
+```cpp
+// Add new test case
+{
+    // Test setup
+    bool testPassed = yourTestLogic();
+    if (!testPassed) {
+        std::cerr << "[FAIL] Your test description\n";
+        ++failures;
+    }
+}
+```
+
+### Rust Tests
+Add to `bridge/src/lib.rs`:
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+    
+    #[test]
+    fn test_your_feature() {
+        // Your test logic
+        assert_eq!(result, expected);
+    }
+}
+```
+
+Run with:
+```bash
+cd bridge
+cargo test
+```
+
+## Future Enhancements
+
+- [ ] Add integration tests with mock Overte server
+- [ ] Add performance benchmarks
+- [ ] Add code coverage reporting
+- [ ] Add automated release builds
+- [ ] Add container-based testing
+- [ ] Add cross-platform testing (macOS, Windows)
