Another method for installation, if you prefer using Cargo, is to install via Git: cargo install --git https://github.com/MystenLabs/walrus --branch mainnet walrus-service --locked. This way, you ensure you get the latest build from the main branch.

If you are using Windows, you can download the latest Walrus executable from this link walrus-mainnet-latest-windows-x86_64.exe. Remember to place walrus.exe somewhere in your PATH.

To update the Walrus CLI, you should remove your current version and reinstall the latest version. You can use the following command to update your existing installation with the latest Mainnet version: curl -sSf https://docs.wal.app/setup/walrus-install.sh | sh -s -- -f. Ensure that your "$HOME"/.local/bin directory is in your $PATH, and then you should be able to run the updated Walrus CLI.
