You will need a Linux environment with Docker. Once you have that, you can set things up:
mkdir -p dependencies export OPENLANE_ROOT=$(pwd)/dependencies/openlane_src # you need to export this whenever you start a new shell export PDK_ROOT=$(pwd)/dependencies/pdks # you need to export this whenever you start a new shell export PDK=gf180mcuC
Next, do a one-time setup of the project.
make setup
