+# Go Plugin
+
+The go plugin provides some extra niceties for using micro with
+the Go programming language. The main thing this plugin does is
+run `gofmt` and `goimports` for you automatically. If you would also
+like automatically error linting, check out the `linter` plugin.
+
+You can run
+
+```
+> gofmt
+```
+
+or
+
+```
+> goimports
+```
+
+To automatically run these when you save the file, use the following
+options:
+
+* `gofmt`: run gofmt on file saved. Default value: `on`
+* `goimports`: run goimports on file saved. Default value: `off`
