+# GitHub Actions Workflows
+
+This directory contains GitHub Actions workflow definitions for automating the build, test, and release processes for the OpenSVM-Dioxus project.
+
+## CI/CD Pipeline (`ci.yml`)
+
+This workflow handles the continuous integration and continuous deployment process for the OpenSVM-Dioxus project.
+
+### Triggers
+
+- **Push** to the `main` branch
+- **Push** of tags matching the pattern `v*` (e.g., `v1.0.0`)
+- **Pull requests** targeting the `main` branch
+
+### Jobs
+
+#### 1. Build & Test
+
+This job builds and tests the application across multiple platforms:
+
+- **Web (WASM)** - Built on Ubuntu
+- **Desktop (macOS)** - Built on macOS
+- **Desktop (Windows)** - Built on Windows
+- **Android** - Built on Ubuntu
+
+Each platform build includes platform-specific optimizations:
+
+- **Web**: WASM optimization with `wasm-opt`
+- **Desktop**: Native CPU instructions with `-C target-cpu=native`
+- **Android**: APK optimization with `zipalign` and `apksigner`
+
+#### 2. Release
+
+This job is triggered only when a tag matching the pattern `v*` is pushed. It:
+
+- Downloads all build artifacts
+- Packages them into platform-specific ZIP files
+- Creates a GitHub release with the packaged artifacts
+- Generates release notes automatically
+
+#### 3. Homebrew Formula Update
+
+This job is triggered only when a tag matching the pattern `v*` is pushed. It:
+
+- Creates or updates a Homebrew formula for the macOS release
+- Calculates the SHA256 hash of the macOS release artifact
+- Creates a pull request to update the formula
+
+#### 4. Android Build
+
+This job builds the Android APK and:
+
+- Optimizes the APK with `zipalign`
+- Signs the APK with a debug key
+- Uploads the APK as an artifact
+- Adds the APK to the GitHub release (if triggered by a tag)
+
+## GitHub Actions Used
+
+This workflow uses the following GitHub Actions:
+
+- `actions/checkout@v4`: Checks out the repository
+- `actions/setup-java@v4`: Sets up JDK for Android builds
+- `actions/cache@v4`: Caches Cargo dependencies for faster builds
+- `actions/upload-artifact@v4`: Uploads build artifacts
+- `actions/download-artifact@v4`: Downloads artifacts for releases
+- `actions-rs/toolchain@v1`: Sets up Rust toolchain
+- `actions-rs/cargo@v1`: Runs Cargo commands
+- `softprops/action-gh-release@v1`: Creates GitHub releases
+- `android-actions/setup-android@v2`: Sets up Android SDK
+
+## Usage
+
+### Regular Development
+
+The CI pipeline will automatically run on all pull requests to validate changes.
+
+### Creating a Release
+
+To create a new release:
+
+1. Create and push a new tag following semantic versioning:
+   ```bash
+   git tag v1.0.0
+   git push origin v1.0.0
+   ```
+
+2. The workflow will automatically:
+   - Build all platform versions
+   - Create a GitHub release with all artifacts
+   - Update the Homebrew formula
+
+### Customizing the Workflow
+
+To modify the workflow:
+
+1. Edit the `.github/workflows/ci.yml` file
+2. Commit and push your changes
+3. The updated workflow will be used for subsequent runs
