-### Dirty fix for libmpfr version
-`sudo ln -s /usr/lib/libmpfr.so.6 /usr/lib/libmpfr.so.4`
+## Steps to getting the GAP SDK run on Linux
+
+In general, follow this README: https://github.com/GreenWaves-Technologies/gap_sdk/blob/master/README.md
+
+PLUS
+
+### Fix the -Werror flag to make openocd compile
 
-### udev rule for FTDI
-```
-touch 90-ftdi_gapuino.rules
-echo 'ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", MODE="0666", GROUP="dialout"'> 90-ftdi_gapuino.rules
-echo 'ATTRS{idVendor}=="15ba", ATTRS{idProduct}=="002b", MODE="0666", GROUP="dialout"'>> 90-ftdi_gapuino.rules
-sudo mv 90-ftdi_gapuino.rules /etc/udev/rules.d/
-sudo udevadm control --reload-rules && sudo udevadm trigger
