@rem Based on the installer found here: https://github.com/Sygil-Dev/sygil-webui
@rem This script will install git and all dependencies
@rem using micromamba (an 8mb static-linked single-file binary, conda replacement).
@rem This enables a user to install this project without manually installing conda and git.
