 hub: git + hub = github
 =======================
 
-`hub` is a command line utility which improves your `git` experience.
+`hub` is a command line utility which injects `git` with GitHub
+knowledge.
 
-The goal is threefold:
-
-* Augment existing `git` subcommands (such as `git clone`) with
-  additional, often GitHub-aware functionality.
-* Clarify many of git's famous error messages.
-* Add new and useful subcommands.
-
-`hub` can be used in place of `git` or you can alias the `git` command in
-your shell to run `hub` - no existing functionality is removed. `hub`
-simply adds and improves.
+It can used on its own or can serve as a complete, backwards
+compatible replacement for the `git` script.
