Want Help with Auto-Script or Docker Setup?

I can give you a ready-to-go installation script or Docker Compose file to spin up Odoo 18 easily.

Bonus Tip

If you're doing this for testing or development, it's better to try Odoo 17 stable now and switch later to 18 when it releases (likely Oct 2025).

Need help setting up this on a VM or configuring it with Nginx, custom addons, etc.?
