+### Step 1: Documentation Hosting
+The first step in showcasing this project involved hosting the DocC-generated documentation for a User API at [https://ayushshrivastv.github.io/OpenAPI-integration-with-DocC/](https://ayushshrivastv.github.io/OpenAPI-integration-with-DocC/). This was achieved through the following process:
+
+1. **Generate SymbolGraph File**:
+   ```bash
+   swift run openapi-to-symbolgraph test/sample-api.json
+   ```
+   This command converts the OpenAPI specification into a SymbolGraph file that DocC can understand.
+
+2. **Convert to HTML Documentation**:
+   ```bash
+   docc convert symbolgraph.json --output-path docs
+   ```
+   This generates the interactive HTML documentation using DocC.
+
+3. **Deploy to GitHub Pages**:
+   - The `docs` folder is deployed to GitHub Pages using the `/docs` source
+   - A landing page (`index.html`) is added to the root, providing easy navigation to the documentation
+   - The documentation is accessible at [https://ayushshrivastv.github.io/OpenAPI-integration-with-DocC/](https://ayushshrivastv.github.io/OpenAPI-integration-with-DocC/)
+
+This implementation demonstrates the basic workflow of converting OpenAPI specifications to DocC documentation and making it accessible through GitHub Pages.
