+The `mqtt` camera platform allows you to integrate the content of an image file sent through MQTT into Home Assistant as a camera. Every time a message under the `topic` in the configuration is received, the image displayed in Home Assistant will also be updated. Messages received on `topic` should contain the full contents of an image file, for example, a JPEG image, without any additional encoding or metadata.
 
 This can be used with an application or a service capable of sending images through MQTT.
