 ## Configuration
 
-To use this module, load `mod_unified_push` in the `modules` section of the config file and add `/up: mod_unified_push` to a listen directive:
+When you install this module, it's enabled by default on port 5283, see `conf/mod_unified_push.yml`
+
+If you want to customize that configuration,
+remove all lines in the file `mod_unified_push.yml` (don't remove the file itself),
+and now you can configure the module in your main `ejabberd.yml` configuration file,
+for example:
 
 ```
+listen:
   -
     port: 5443
     ip: "::"
     module: ejabberd_http
     tls: true
-    protocol_options: 'TLS_OPTIONS'
     request_handlers:
       /api: mod_http_api
       /bosh: mod_bosh
+      /up: mod_unified_push
       /upload: mod_http_upload
       /ws: ejabberd_http_ws
-      /up: mod_unified_push
-```
 
-Once the config has been reloaded, the server can be added as a Unified Push distributor in the settings of Conversations, using the same domain used for the JID.
