Modules are installed using git by default. If you don't have git installed, or if you want to take advantage of our degit tool for faster and lighter module installations, you can set degit as the default tool with:

zstyle ':zim:zmodule' use 'degit'

By default, zimfw will check if it has a new version available every 30 days. This can be disabled with:

zstyle ':zim' disable-version-check yes
