 Configuration for Arduino
 --------------
-If building using the Arduino IDE, `r65emu/hw/user.h` must be configured correctly.
+If building using the Arduino IDE, `r65emu/src/hw/user.h` must be configured correctly.
 
 Currently the only mass-produced board which is supported is the 
 [LilyGO TTGO](https://www.tinytronics.nl/shop/en/development-boards/microcontroller-boards/with-wi-fi/lilygo-ttgo-vga32-esp32).
 
 Examples are also given for a generic `node32s` board and a homebrew `esp8bit` board.
 
-Copy your configuration file to `user.h`. If the board is also mass-produced, please open a PR to add the new file to the library.

 Some emulations require a filesystem image containing programs to be uploaded:
 - On esp32, this [arduino plugin](https://github.com/me-no-dev/arduino-esp32fs-plugin) is required for that
