+# Docker Support
+
+Running local build with Docker
+
+```shell
+npm run build
+```
+
+The application is already preconfigured to run alongside backend containers within the Docker Compose.
+
+If you need to provide custom settings, update `dist/content-ce/app.config.json` file.
+See [Configuration](/configuration/) section for more details
+
+Build and run the container:
+
+```shell
+./docker/run.sh
+```
+
+The application is configured to run at `http://localhost:8081`.
+
+## Containerized Deployment
+
+Typically, you do not need changing application configuration when running ACA in the containerized deployment scenario.
+All defaults are already preconfigured and pointing to the locally running Nginx proxy.
+
+Please refer to [ACS Deployment](https://github.com/Alfresco/acs-deployment)
+and [ACS Docker Compose](https://github.com/Alfresco/acs-deployment/tree/master/docs/docker-compose) for more details.
+
+## Building manually
+
+Update `dist/content-ce/app.config.json` if needed.
+
+```shell
+# cleanup previous
+docker rmi -f alfresco/alfresco-content-app
+
+# build
+docker build -t alfresco/alfresco-content-app .
+```
+
+You can now run this locally:
+
+```shell
+docker run --rm -it --user 1000:1000 --publish 8081:8080 alfresco/alfresco-content-app
+```
+
+Navigate to `http://localhost:8081`.
