To install a new module:

1 - add the module into odoo's addons folder

   - Or add it to a new custom folder and give its path in your conf file

2 - Activate developer mode and upgrade your module list

3 - your module will be now available in your apps list [If your module is not catogerised as an app remove Apps from the filter
