download the .tar.gz for your platform, and unpack it to
-your desired location. Then, use the `RISC_PREFIX` and `RISCV_OPENOCD_PREFIX`
+your desired location. Then, use the `RISC_PATH` and `RISCV_OPENOCD_PATH`
variables when attempting to use the tools:
```
cp openocd-<date>-<platform>.tar.gz /my/desired/location/
-cp riscv-gnu-toolchain-<date>-<platform>.tar.gz /my/desired/location
+cp riscv64-unknown-elf-gcc-<date>-<platform>.tar.gz /my/desired/location
cd /my/desired/location
tar -xvf openocd-<date>-<platform>.tar.gz
-tar -xvf riscv-gnu-toolchain-<date>-<platform>.tar.gz
-export RISCV_OPENOCD_PREFIX /my/desired/location/openocd
-export RISCV_PREFIX /my/desired/location/riscv-gnu-toolchain
+tar -xvf riscv64-unknown-elf-gcc-<date>-<platform>.tar.gz
