-Board Support Package
\ No newline at end of file
+This is our "Board Support Package" repository.
+
+In the "Driver" folder, you will find the layer of code that interacts directly with the HAL Libraries and the DJI Boards.
+
+In the "Device" folder, you will find a layer of code that interacts with the Driver layer, and that represents different devices in our robots' system : the OLED board, the DT7 controller, and more.
