Introduction

Before opening Odoo for the first time, before setting up a warehouse or issuing an invoice, it is worth pausing for a moment to ask a question we rarely stop to consider: where does the software we use every day come from? Who built it? And why do some programs cost thousands of euros a year while others, just as powerful, are completely free?

The answer to these questions is not to be found in a technical manual. It is found in a story. A story that begins with a jammed printer in an MIT laboratory in 1980, continues with a 21-year-old Finnish student who posted a modest message on an internet forum, and reaches all the way to the ERP you are going to learn to use in this course. It is a story about people who decided that knowledge should be shared, not locked away. And that decision changed the world.

We begin here because understanding this story is not an academic exercise: it is the key to understanding why your company can today gain access to a complete business management system without paying a single euro in licences. And why that does not mean it is any worse, but quite the opposite.
