I will not explain how to install the different Odoo repository but rather, I will present you different tools you can use to make the development process easier.

Odev is a tool created by one of our colleagues to help with our databases. You can create new local databases, remove them, list them, get a dump from an Odoo online db, etc... You can find more explainations on how to install and use Odev here

Export is a tool created by another one of our colleagues to help you with the process of developing a task. When a task has been analysed with the ps-tools program, you can scaffold it and Export will generate a module with all the information present in the analysis. You can access the repository here

To help with your formation, we have designed a simple but useful task. You must start with reading and understanding what the need is, because without a clear image of what the final goal is, you will not be as efficent as needed. The second thing to do if the task has been analysed with the ps-tools program is to scaffold it. This is where the Export tool comes in play.
