Steps to Learn Odoo Module Development:

1. Set Up Odoo Locally
   Install Odoo (preferably version 16 or 17) with required dependencies (Python, PostgreSQL).
2. Understand the Folder Structure
   A basic module includes:
   • __manifest__.py: Module metadata
   • __init__.py: Python package initializer
   • models/: Python business logic
   • views/: XML files for UI
   • security/: Access rules and permissions
3. Start with a Simple Module
   Create a "To-Do List" or "Library Management" app to learn model-view-controller structure.
4. Use Odoo Studio (Optional)
   Try Odoo Studio to visualize UI and field additions before doing it in code.
5. Follow Official Documentation
   Odoo Developer Docs
6. Join the Community
   Engage with Odoo Forums, GitHub, or Reddit r/Odoo
7. Practice Daily
   Keep building and customizing real features — it's the fastest way to learn.
