Hi,

Seems you are looking to install a custom module to your system. For this the steps are:

* Create  a new folder to place the custom modules

* Specify the above path in the conf file

* Place the modules in the folder

* Restart the service and activate the developer mode and click the Update Apps List Menu.

Now you can search your  module in the apps menu and install it. If you didn't succeed with the above steps, see this video for better understanding: How to Download and Install Module From Odoo App Store

Thanks
