-A tag is a label that can be applied to a resource (currently Droplets, images,
-volumes, volume snapshots, and database clusters) in order to better organize or
-facilitate the lookups and actions on it.
+Tags are labels that you can apply to resources to better organize them and more efficiently take actions on them. For example, if you have a group of Droplets that you want to place behind the same set of cloud firewall rules, you can tag those Droplets with a common tag and then apply the firewall rules to all Droplets with that tag.
 
 Tags have two attributes: a user defined name attribute and an embedded
 resources attribute with information about resources that have been tagged.`,
