+# What is GitReleaseManager?
+
+GitReleaseManager is a tool that will help create a set of release notes for your application/product.  It does this using the collection of issues which are stored on the GitHub Issue Tracker for your application/product.
+
+By inspecting the issues that have been assigned to a particular milestone, GitReleaseManager creates a set of release notes, in markdown format, which are then used to create a Release on GitHub.
+
+In addition to creating a Release, GitReleaseManager can be used to publish a release, close a milestone, and also to export the complete set of release notes for your application/product.
