 ### Build and flash instructions
 
-1. An Arduino like bar can be seen at the top, which can be used to compile the software and flash it to the board. The check symbol is used to compile while the right arrow symbol is used to flash the software. There are also symbols to open the serial monitor or the serial plot.
