+# GitHub Actions Workflows
+
+This directory contains GitHub Actions workflows for CI automation.
+
+## CI Workflow (`ci.yml`)
+
+**Triggers**: On push to `main` and on pull requests
+
+**Jobs**:
+- **Test**: Runs all unit tests
+- **Lint**: Runs ESLint and TypeScript type checking
+
+## Local Development
+
+To run the same checks locally before pushing:
+
+```bash
+# Run all tests
+npm test
+
+# Run linting
+npm run lint
+
+# Check types
+npm run typecheck
+```
