Hai louie,

    There is no need to create or add the path to the conf file, you just create a new folder and give the path of that folder in the config file.

addons_path = /../../odoo/addons, /../../odoo/<custom_addons>

And every new module that you created yourself or downloaded from odoo apps .

that module adds into the newly created folder. then just restart your services and update the apps. You can see the apps appear in the app store.

Just follow this link it will help you more.
