+**Docker**
+Docker users running X-Server can run cool-retro-term in an isolated Docker container using the following command.  Please note that hardware and x-server resources need to be  mounted inside the container in order for the container to have access to hardware acceleration and X-server resources.  Furthermore, preserving user profile settings within the cool-retro-term container requires a volume mount from your local home directory to the `user` home directory within the container:
+
+```sh
+#Create the application settings directory:
+mkdir -p ~/.local/share/cool-retro-term
+
+#Run cool-retro-term:
+docker run -it --privileged --rm -e DISPLAY=$DISPLAY -e XDG_RUNTIME_DIR=/run/user/1000 -e XAUTHORITY=$XAUTHORITY -v /run/user/1000:/run/user/1000 -v /tmp/.X11-unix:/tmp/.X11-unix -v /dev/dri:/dev/dri -v ~/.local/share/cool-retro-term:/home/user/.local/share/cool-retro-term quay.io/aric49/crt:latest

+## Build Instructions Docker
+Clone the primary repository with the `--recursive` flag, and perform a Docker build.  Docker will automatically compile the code inside a Docker container.  To run the docker container, you need to mount X-Server resources and your video card inside the Docker container so that Docker can initiate the GUI and successfully start cool-retro-term with hardware acceleration:
+
+```sh
+#Git clone
+git clone --recursive https://github.com/Swordfish90/cool-retro-term.git
+
+#Docker Build
+docker build -t cool-retro-term:1
+
+#Run the built image. 
+docker run -it --privileged --rm -e DISPLAY=$DISPLAY -e XDG_RUNTIME_DIR=/run/user/1000 -e XAUTHORITY=$XAUTHORITY -v /run/user/1000:/run/user/1000 -v /tmp/.X11-unix:/tmp/.X11-unix -v /dev/dri:/dev/dri -v ~/.local/share/cool-retro-term:/home/user/.local/share/cool-retro-term cool-retro-term:1
