How To Install Custom Module in Odoo

How to process on code source Odoo entreprise installed on vps ?

Thank you for your video,
I have some concerns, I want to remove column tax on invoices, and add column id products on the invoices.

good tutorial but you should have opened your odoo.conf file so that we can do a reference

Good tutorials.. I tried create a custom module directory and add that path in the config file ..but it was not working. Instead I add my custom module in default addon directory and given absolute path of the module in config file..it was working.. is there anything else I have to do to make custom directory.

Для добавления в версии 13 закидывать в дирректорию /odoo13/server/odoo/addons тогда будет отображаться после перезагрузки и обновления списка

After installing module it's not showing with rest installed odoo apps icon like sales,discuss,website..

Amazing tutorials! can you make tutorial on Sale Analysis.?
