For now, you can only install it by downloading sources from github. Later on, the plugin should be on GLPI plugins.
- Git client
- GLPI installed >= 9.1
Go into GLPI plugins directory, then get the lastest version of plugin sources on github :
git clone -b DEV https://github.com/armadito/armadito-glpi armadito
Then, after logging into GLPI you should be able to install and enable Armadito Plugin. To do this, go to Setup > Plugins and select Armadito.
