I've re-jigged the run man page so that each option's text begins with the cli's help text for that flag, and then ay subsequent lines in the man page are carried forward.

NAME
docker-attach - Attach to a running container
SYNOPSIS
docker attach [--no-stdin[=false]] [--sig-proxy[=true]] CONTAINER
DESCRIPTION
If you docker run a container in detached mode (-d), you can reattach to the detached container with docker attach using the container's ID or name.
You can detach from the container again (and leave it running) with CTRL-p CTRL-q (for a quiet exit), or CTRL-c which will send a SIGKILL to the
container, or CTRL-\ to get a stacktrace of the Docker client when it quits.
When you detach from a container the exit code will be returned to
the client.
OPTIONS
--no-stdin=true|false Do not attach STDIN. The default is false.
--sig-proxy=true|false Proxy all received signals to the process (non-TTY mode only). SIGCHLD, SIGKILL, and SIGSTOP are not proxied. The default is true.
EXAMPLES
Attaching to a container
In this example the top command is run inside a container, from an image called fedora, in detached mode. The ID from the container is passed into the docker attach command:
# ID=$(sudo docker run -d fedora /usr/bin/top -b)
# sudo docker attach $ID
