 ## What is Jekyll?
 
 Jekyll is a static site generator. It takes text written in your favorite markup language and uses layouts to create a static website. You can tweak the site’s look and feel, URLs, the data displayed on the page, and more.
 
 Quoted from https://jekyllrb.com/docs/
 
+## Docker quickstart
+You may run Jekyll to serve the CodeWith website locally via docker
+
+You must first install [Docker](https://www.docker.com/) for your operating system.
+
+Next, you must then build the docker container, 
+that will install the dependencies required for the application to run. You will need to run this command
+at any point the Dockerfile changes to ensure you have the latest version of the container.
+
+```bash
+docker build . -f docker/bundle.Dockerfile --tag 'codewithgroup-website'
+```
+
+At any point at which you then want to run the server, use
+
+```bash
+docker run -it -v .:/app -p 127.0.0.1:4000:4000 codewithgroup-website
+```
+
+Despite what the output may say, you will access the CodeWith website at `127.0.0.1:4000`
+
+Changes to files within the project will prompt a recompile after some time, you'll need to refresh the page
+you're viewing in the browser to see the changes.
