 - To install FDRS, download the project folder by clicking the “Clone or download” button and then clicking “Download ZIP”. You should then move it to your Arduino 'libraries' folder to complete the installation.
 - After installing, edit the 'src/fdrs_globals.h' file with your WiFi credentials and other global parameters.
 - To begin, flash an ESP device with the **1_UART_Gateway.ino** example, and another with the **ESPNOW_Sensor.ino** example. The mocked-up sensor readings will be received by the gateway and relayed to the serial port, where it may be monitored via a terminal.
-- If you would like to use MQTT, you can connect a second ESP via the Rx and Tx pins (crossed), and flash it with the "0_MQTT_Gateway.ino" example. If your WiFi and MQTT configurations are correct, data will be published to the topic 'fdrs/data'.
