+### Automated Indentation
+
+The default indentation configuration of company-coq is not compatible with the Iris syntax.
+As a result, automatic indentation will indent lines incorrectly.
+
+To solve some of these indentation errors you can add the following line to your Emacs
+initialisation file:
+```
+(setq coq-smie-user-tokens
+	'(("∗" . "*")
+	  ("-∗" . "->")
+	  ("∗-∗" . "<->")
+	  ("==∗" . "->")
+	  ("⊢" . "->")
+	  ("⊣⊢" . "<->")
+	  ("⋅" . "*")
+	  (":>" . ":=")))
+```
+This will let the indentation strategy treat the Iris symbols (e.g. `-∗`) similar to the
+closely related Coq symbols (e.g. `->`).
