Odoo help needed

Hi everyone,

I have a client who needs a custom CRM/ERP system, and I'm considering building something on Odoo for them. Additionally, I want to develop this as my own product for future use. However, I'm not very familiar with Odoo and could use some guidance.

Questions:

1. Should I clone Odoo's code and deploy it on a server, then use Odoo Studio to build custom apps? Or is there a better approach?
2. Are there any resources where I can find built-in apps that I can import into our private server(odoo apps)?

Any advice or resources would be greatly appreciated!

Thanks in advance!
