1. There is no need to include a copy of docker-compose.yml in the README file. It's just a duplication that would need to be updated. Please remove that section.
2. "To verify that you docker put the following command below" - ??
3. Remove "Github user who updated this markdown:" heading and section - no personal accreditations.
4. Adjust table of contents accordingly.
5. Change restart: unless-stopped back to restart: always - no data must be left on the filesystem when you are not using it. The current version of Firefox allows you to update the browser without killing the container. If you would like a permanant update, then you must rebuild it. The rebuild will pick up the latest OS updates as well.
6. Revert "Provides direct access to the NoVNC server" back to "Provides direct access to the VNC server" - it is a VNC server. NoVNC is a client.
