+# GitHub Actions Setup Guide
+
+This project uses [GameCI](https://game.ci/) for Unity CI/CD.
+
+## Required Secrets
+
+You need to configure the following secrets in your GitHub repository settings:
+
+### Option 1: Unity License File (Recommended)
+
+1. **UNITY_LICENSE**: Your Unity license file content (`.ulf` file)
+
+To get your license file:
+
+```bash
+# Run Unity activation locally
+docker run -it --rm \
+  -e UNITY_VERSION=6000.0.58f2 \
+  -e UNITY_EMAIL=your@email.com \
+  -e UNITY_PASSWORD=yourpassword \
+  unityci/editor:ubuntu-6000.0.58f2-base-3 \
+  unity-editor -quit -batchmode -nographics \
+  -logFile /dev/stdout \
+  -createManualActivationFile
+```
+
+Then activate manually at [license.unity3d.com](https://license.unity3d.com/) and add the resulting `.ulf` file content as the `UNITY_LICENSE` secret.
+
+### Option 2: Unity Credentials
+
+- **UNITY_EMAIL**: Your Unity account email
+- **UNITY_PASSWORD**: Your Unity account password
+
+Note: This option may not work with 2FA enabled.
+
+## Workflows
+
+### unity.yml
+
+Main CI workflow that runs on push and pull requests:
+
+1. **Test Job**: Runs all EditMode tests
+2. **Build Job**: Creates Windows (Mono) build (only runs if tests pass)
+
+### Triggers
+
+- Push to `main`, `develop`, or `feature/**` branches
+- Pull requests to `main` or `develop`
+- Manual trigger via workflow_dispatch
+
+## Artifacts
+
+- **Test Results**: Test output and coverage reports
+- **Build-Windows-Mono**: Windows executable build
+
+## Important: ONNX Models
+
+ONNX model files (`.onnx`) are **not tracked in git** due to their large size (~4GB total).
+
+### Impact on CI
+
+- **Tests**: Model-dependent tests will fail without ONNX files
+- **Build**: Compilation will succeed, but runtime requires models
+
+### Solutions
+
+1. **Git LFS** (Recommended for private repos):
+   ```bash
+   git lfs install
+   git lfs track "*.onnx"
+   git add .gitattributes
+   git add Assets/Models/*.onnx
+   git commit -m "Add ONNX models with LFS"
+   ```
+
+2. **External Storage**: Download models in CI workflow from cloud storage (S3, GCS, etc.)
+
+3. **Skip Model Tests**: Add `[Category("RequiresModels")]` attribute to tests and exclude in CI
+
+### Current Workflow Behavior
+
+The workflow will attempt to run all tests. Tests that require ONNX models may fail if models are not available. This is expected behavior for repositories without model files.
+
+## Notes
+
+- Consider using Git LFS for large model files if full CI testing is needed
+- The build artifact will not include ONNX models unless they are tracked
