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-tag - Tag an image into a repository
SYNOPSIS
docker tag [-f|--force[=false]] IMAGE[:TAG] [REGISTRYHOST/][USERNAME/]NAME[:TAG]
DESCRIPTION
This will give a new alias to an image in the repository. This refers to the entire image name including the optional TAG after the ':'.
"OPTIONS"
-f, --force=true|false When set to true, force the alias. The default is false.
REGISTRYHOST The hostname of the registry if required. This may also include the port separated by a ':'
USERNAME The username or other qualifying identifier for the image.
NAME The image name.
TAG The tag you are assigning to the image. Though this is arbitrary it is recommended to be used for a version to distinguish images with the same name. Note that here TAG is a part of the overall name or "tag".
OPTIONS
-f, --force=true|false Force. The default is false.
EXAMPLES
Giving an image a new alias
Here is an example of aliasing an image (e.g., 0e5574283393) as "httpd" and tagging it into the "fedora" repository with "version1.0":
docker tag 0e5574283393 fedora/httpd:version1.0
Tagging an image for a private repository
To push an image to an private registry and not the central Docker registry you must tag it with the registry hostname and port (if needed).
docker tag 0e5574283393 myregistryhost:5000/fedora/httpd:version1.0
