 # The code below will cut version displayed in the dropdown like this:
-# tags like v0.1.0 = > 0.1
-# main will remain main
-# if not set will fail back to main
+# By default, set to "main".
+# If it's a tag like refs/tags/v1.2.3-rc4 or refs/tags/v1.2.3, then
+# cut to v1.2
 # the version varible is used in layout.html: https://github.com/pytorch/executorch/blob/main/docs/source/_templates/layout.html#L29
