 # Version Increment ➕
 
+This action calculates the next version based on existing Git tags.
+
+Intentionally, this action does not create tags.  It's suggested to use an
+action dedicated to creating tags in a step following the successful steps
+that make up your test, build and releasing process.  See the example below.
