 GPIOs are configured by assigning predefined values for each IO in the file `verilog/rtl/user_defines.v <https://github.com/efabless/caravel_user_project/blob/main/verilog/rtl/user_defines.v>`_ in your project.
 
-You need to assigned configuration values for GPIO[5] thru GPIO[37].  GPIO[0] thru GPIO[4] are preset and cannot be changed.
