I think the Build the official NGINX Agent image with Docker section should be removed and replaced with how to pull the official NGINX Agent images.

This all looks good. One thing for the "Run the NGINX Agent container" section. Should we give another command so an end user knows how to mount an nginx-agent.conf file?

When running docker run --name nginx-agent -d nginx-agent Agent has default config
Could provide this command to mount a user's nginx-agent.conf file

docker run --name nginx-agent -d \
  -v /path/to/your/nginx-agent.conf:/etc/nginx-agent/nginx-agent.conf \
  nginx-agent
