• Setup WSL2 (default for win11)
• Install Ubuntu 22.04 (wsl --install -d Ubuntu-22.04)
• Install Docker Desktop for Windows for WSL2

In WSL terminal:

• git clone https://github.com/bloxbean/yaci-devkit.git
• replace in yaci-devkit/start.sh source ./info.sh with . ./info.sh
• run sudo ./start.sh in yaci-devkit folder from wsl
• run sudo ./yaci-start.sh to run the cli in the container
• yaci-cli:> create-node -o --start # will start cardano node

Useful commands:

• tip # get the tip of the blockchain
• exit # stop and clear the node
• reset # reset the node from the genesis block
• stop # stop the node but sometimes after stop it is hard to start the node so use reset
