+## A note about gomods and prefixed tags
+
+!!! note
+
+ If you have a `github.com/user/repo/moda` module, its tags should be named
+ `moda/v1.2.3`.
+ This will allow users to `go get github.com/user/repo/[email protected]`, and
+ everything should work as you'd expect.
+
+!!! warning
+
+ Tag prefixes that do not match the module name are not supported by go mods.
