Niyas Raphy, 

                    Is that the same way with openeducat? how can i do with command lines? Thank you for helping me.

Hi,

You have to add this downloaded module to your addons path and restart the odoo service, then go to the odoo user interface and activate the developer mode and go to apps menu and click Update Apps List menu and search your module in the apps menu and install it.

You can check this video explaining the same: https://www.youtube.com/watch?v=KCGAKbVT92k

Thanks
