+[Github Repo](https://github.com/m-housh/swift-cli-version)
+
+## Overview
+
+This tool exposes several plugins that can be used to derive a version for a command line program at
+build time or by manually running the plugin. The version is derived from git tags and falling back
+to the branch and git sha if a tag is not set for the current worktree state.

-Derive a version for a command line tool from git tags or a git sha.
-
-## Additional Resources
-
-[Github Repo](https://github.com/m-housh/swift-cli-version)
-
-## Overview
-
-This tool exposes several plugins that can be used to derive a version for a command line program at
-build time or by manually running the plugin.  The version is derived from git tags and falling back to 
-the branch and git sha if a tag is not set for the current worktree state.
