 ## Features
- -  🌡️  Adds the internal temperature readout of the chip to the `Info` tab
+ - 🌡️ Adds the internal temperature readout of the chip to the `Info` tab
  - 🥵 High temperature indicator/action. (Configurable threshold and preset)
  - 📣 Publishes the internal temperature over the MQTT topic: `mcutemp`
-<br><br>
+
 
 ## Use Examples
 - Warn of excessive/damaging temperatures by the triggering of a 'warning' preset
 - Activate a cooling fan (when used with the multi-relay usermod)
-<br><br>
+
 
 ## Compatibility
 - A shown temp of 53,33°C might indicate that the internal temp is not supported
 - ESP8266 does not have a internal temp sensor -> Disabled (Indicated with a readout of '-1')
 - ESP32S2 seems to crash on reading the sensor -> Disabled (Indicated with a readout of '-1')
-<br><br>
+
 
 ## Installation
 - Add a build flag `-D USERMOD_INTERNAL_TEMPERATURE` to your `platformio.ini` (or `platformio_override.ini`).
