Installation and Upgrading

# Substitute ~ for the home directory of the user that runs ejabberd:
cd ~/.ejabberd-modules/sources/
git clone https://github.com/proger/mod_trunk
# ejabberdctl should now list mod_trunk as available:
ejabberdctl modules_available
# Compile and install mod_trunk:
ejabberdctl module_install mod_trunk
# To upgrade, same as uninstall + install:
ejabberdctl module_upgrade mod_trunk
