 # Overview
+
 This is a very simple, bare-bones NodeJS project created for you to use with Docker.
 
-# Local Setup
-* Install dependencies: `npm install`
-* Run server: `node server.js`
+## Local Setup
+
+**_Note_**: This is only needed if you want to run the app locally. You don't need to install the dependencies or run the server if you are running the code inside a Docker container.
+
+- Install dependencies: `npm install`
+- Run server: `node server.js`
+
+## Container Setup
+
+- Build image: `docker build .`
+- Run container with image: `docker run {image_id}` where `image_id` can be retrieved by running `docker images` and found under the column `IMAGE ID`
+- You can use the `-d` flag to run the container in the background. This will enable you to run other commands in your terminal while the container is running.
