-I do mention the platform configuration here for completeness sake, but **generally you will not have
-to add the following configuration option to your yaml file**. It is loaded automatically by the
-components that need it, and the GPIO + I2C configurations are fully prepared to work for the
-Bedside Lamp 2 wiring out of the box. Therefore, you will not find this piece of configuration in
-the [`example.yaml`](../example.yaml).

+You will not have to add any configuration options for the `xiaomi_bslamp2` to your yaml file.
+The required configuration is fully provided by the configuration package `packages/core.yaml`.

 ```yaml
 xiaomi_bslamp2:
-  # Options for the RGBWW LEDs HAL.
-  red: "GPIO13"
-  green: "GPIO14"
-  blue: "GPIO5"
-  white: "GPIO12"
-  master_1: "GPIO33"
-  master_2: "GPIO4"

 The only reason that I can think of for adding this platform configuration to your yaml file, would
