I've noticed two issues in "Install using Docker" section.

There is only a single line instruction which shows how to pull the image.
There is no run command that shows which arguments are needed for running a Promtail Docker container.

Another smaller issue is the comment above the "docker pull" line which gets copied into your clipboard when you want to
copy the pull command.
