   ## Examples
 
   When a process reaches its end, by default it exits with
-  reason `:normal`. You can also call it explicitly if you
+  reason `:normal`. You can also call `exit/1` explicitly if you
   want to terminate a process but not signal any failure:
 
       exit(:normal)


      exit(:seems_bad)

  If the reason is not `:normal`, all linked process to the
  exited process will crash (unless they are trapping exits).

  ## OTP exits

  Exits are used by OTP to determine if a process exited abnormally
  or not. The following exits are considered "normal":

    * `exit(:normal)`
