I think I'm stupid, but I can't understand how to install new modules on OpenErp 7.0. I downloaded the modules from github and put them in the addons folder. I've read somewhere that I should click "update module list" or something like that under settings which is something I can't see anywhere.

Could someone please explain the correct procedure for Openerp 7.0 under Windows ? It can't be that difficult !!!! Damn, I just wanted to install the software to show it to my students :-(

PS: Am I doing right in downloading from Github ?

Thanks.
