+# Swagger/OpenAPI Example
+
+This directory contains an OpenAPI 3.0 specification file that demonstrates rich API documentation suitable for use with SwaggerUI.
+We then run Bazel actions to run the docgen tool and stitch into the parent repository's documentation site.
+
+## Files
+
+- `openapi.yaml` - Complete OpenAPI 3.0 specification for a Task Management API
+
+## Features Demonstrated
+
+The OpenAPI specification includes:
+
+- **Comprehensive API Documentation**: Rich descriptions for all endpoints, parameters, and schemas
+- **Multiple Endpoints**: CRUD operations for tasks, projects, and users
+- **Request/Response Examples**: Multiple examples for different use cases
+- **Detailed Schemas**: Well-documented data models with validation rules
+- **Error Responses**: Standardized error response formats
+- **Authentication**: Bearer token authentication scheme
+- **Pagination**: Pagination support for list endpoints
+- **Filtering & Sorting**: Query parameters for filtering and sorting results
+
+## Viewing with SwaggerUI
+
+Run `bazel run mkdocs.serve`
+
+Then open http://localhost:8080
+
+## API Overview
+
+The Task Management API provides:
+
+- **Tasks**: Create, read, update, and delete tasks with status, priority, assignments, and due dates
+- **Projects**: Organize tasks into projects
+- **Users**: Manage users who can be assigned to tasks
+
+All endpoints require Bearer token authentication and return JSON responses.
