Install : Not straight forward to install on Windows (Git-bash)

[geraudloup]

• Install should be easy on Windows with standard install of git (which is git-bash) => one liner to copy-paste
• It should not use make (which is not shipped with git-bash)
• It should work to update the version (so install on already installed should update the version of git-standup
• Documentation should be updated to relevant changes
