+# goenv
+
+This plugin looks for [goenv](https://github.com/syndbg/goenv), a Simple Go-lang version
+management system, and loads it if it's found.
+
+To use it, add `goenv` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... goenv)
+```
+
+## Functions
+
+- `goenv_prompt_info`: displays the Go-lang version in use by goenv; or the global Go-lang
+  version, if goenv wasn't found.
