+# 0) This setup is intended for Desktop use by your local user and not root.
+# It will spawn a docker container that will use your Xsession to run the chromium browser
+# Your user is assumed to have permission to run and build containers
+
+# 1) Go into the source directory of this app 'chromium' and copy it into your docker environment:
+# You can use your own path but will need to adjust the below lines and any affected dependant files accordingly
+$ cp . /var/lib/docker/configs/chromium/
+$ cd /var/lib/docker/configs/chromium/
+
+# 2) Configure the host environment for the container before starting it
+# Run 'xauth list' on the Docker host as the user that will run the container (not root, unless root runs X on your system)
+# Copy the whole line that was produced by the above command and save it into the xcookie in the source directory of this app
+
+# 3) Build your container
+$ docker build -t . chromium
+
+# 4) Create the below directories within /var/lib/docker/configs/pass/data
+# If using a different path to store your containers configurations and data files you will need to modify the paths in the 'firefox-container' script too
+$ mkdir -p /var/lib/docker/configs/pass/data/{cache,config,pki}
+# Create a directory to keep the downloads of your container locally:
+$ mkdir -p /home/$USER/Downloads/chromium-container
+
+# 5) Start your container with:
+$ chromium-container
+
+# 6) Optionally you can move the start-pass script somewhere inside of your path
+$ sudo cp chromium-container /usr/loca/bin
+$ sudo chmod -v 0755 /usr/loca/bin/chromium-container
