+- Support for serverless SSR build
+- Auto-detected when deploying
+- Minimal configuration required
+::
+
+### Setup
+
+Azure Static Web Apps are designed to be deployed continuously in a [GitHub Actions workflow](https://docs.microsoft.com/en-us/azure/static-web-apps/github-actions-workflow). By default, Nitro will detect this deployment environment and enable the `azure` preset.
+
+### Local preview
+
+You can invoke a development environment to preview before deploying.
+
+```bash
+NITRO_PRESET=azure yarn build
+npx @azure/static-web-apps-cli start .output/public --api-location .output/server
+```
+
+### Deploy from CI/CD via GitHub Actions
+
+When you link your GitHub repository to Azure Static Web Apps, a workflow file is added to the repository.
+
+Find the build configuration section in this workflow and update the build configuration:
+
+```yml{}[.github/workflows/azure-static-web-apps-<RANDOM_NAME>.yml]
+###### Repository/Build Configurations ######
+app_location: '/'
+api_location: '.output/server'
+output_location: '.output/public'
+###### End of Repository/Build Configurations ######
+```
+
+**Note**
+
+Pending an update in the [Azure Static Web Apps workflow](https://github.com/Azure/static-web-apps-deploy), you will also need to run the following in your root directory:
+```bash
+mkdir -p .output/server
+touch .output/server/.gitkeep
+git add -f .output/server/.gitkeep
+```
+
+That's it! Now Azure Static Web Apps will automatically deploy your Nitro-powered Nuxt application on push.
