-## Access your RF24Network sensors using a web browser
+## Easily create home automation scenarios and sensor networks
 
-### Current stage: Functional & Stable (Updated 2021)
+### Updated 2023:
 
 RF24Ethernet requires the RF24, RF24Network and RF24Mesh libraries
 
 Documentation & Setup Info: http://nRF24.github.io/RF24Ethernet
 
 Downloads: http://tmrh20.github.io/
 
+Note: Recent changes to support NRF5x boards prevent usage of RF24 devices with NRF5x boards. Users must use the internal radio with RF24Ethernet.
+See the [nrf_to_nrf Arduino library](https://github.com/TMRh20/nrf_to_nrf).
