 This aims to control a Libratone Zipp speaker within [Home Assistant](https://www.home-assistant.io/) using [this Python library](https://github.com/Chouffy/python_libratone_zipp).
 
-Prerequisites:
-
-* the [python-libratone-zipp](https://pypi.org/project/python-libratone-zipp/) library
-* you may need to forward `3333/udp` and `7778/udp`
-
 ## Usage
 
 ### Installation via [HACS](https://hacs.xyz/)
 
-1. Either
-    * HACS installation: add `https://github.com/Chouffy/home_assistant_libratone_zipp` as a custom repository with *integration* type
-    * Manual installation: Copy `/custom_components/*` in your `/config/custom_components/` directory of Home Assistant.
+1. Add this repository `https://github.com/Chouffy/home_assistant_libratone_zipp` as a custom repository with *integration* type
 1. Click *Install*
 1. Add the following in your `/config/configuration.yaml`:
 
     ```yaml
     media_player:
-      - platform: libratone_zipp
-        host: 192.168.X.X
-        name: "Zipp"
+    - platform: libratone_zipp
+        host: 192.168.XX.XX
+        name: Zipp
+        scan_interval: 2
     ```
 
-    * You can also add `scan_interval: 2` below `name` if you want higher refresh rate
+    * I suggest `scan_interval: 2` to get 2 seconds refresh rate
 
 1. Restart the server
+1. You need to forward `3333/udp` and `7778/udp` if you're using Docker/devcontainer
