node -v Start with a Fuel template and name it sway-store.
pnpm create fuels --pnpm sway-store Go into the sway-store folder:
cd sway-store There should already be a folder called sway-programs inside, where your Sway programs will live. Ignore the other programs as we will only focus on the contract program type in this tutorial. Move into your contract folder:
