+## Docker Setup
+
+There is also the option to develop and build the application using Docker.
+
+The application's [Dockerfile](Dockerfile) is a multi-stage Dockerfile. It has a base development image that can be used in a dev environemt, this base image contains all projects's dependencies. The production image only has the application and necessary libs to serve the app in a production environment.
+
+It is possible to build the production image with the following command:
+
+```
+docker build -t sticky-web-client-prod .
+```
+
+In order to run the application you can eith run:
+
+```
+docker run -it -p 80:80 --rm sticky-web-client-prod
+```
+
+If you wish to build the development image you only need to add the target flag with the image name:
+
+```
+docker build --target dev -t sticky-web-client-dev .
+```
+
+And to use ir for development you can bind a volume to the project folder and add the HOST variable to enable Hot Reload:
+
+```
+docker run -it -p 8080:8080 -v $(pwd)/src:/app/src -e HOST=0.0.0.0 --rm sticky-web-client-dev
+```
