+Utop in emacs also supports TAB-completion. If your version of emacs includes `company` completion will appear at the code point. Otherwise completion will appear in a separate buffer. In the case of `company` a hook **must** be added to enable `company` as a minor mode when running utop in major mode. To enable please add the following to your `~/.emacs`:
+
+```elisp
+  (add-hook 'utop-mode-hook 'company-mode)
+```
+
 ### Usage
 
 Then you can execute utop inside emacs with: `M-x utop`.
