Why people and companies contribute

Open source means code published under a licence, a set of rules that lets anyone use, study, change and share it. It runs most of the software you touch: Linux, Python, React, even Git itself. There are several reasons why people contribute.

Some want to fix a bug that affects them. Some want to learn from experienced reviewers, or build a public record of real work. Others contribute because their employer depends on the project.

Companies pay engineers to contribute so they can shape tools they rely on and share the cost of keeping them working. These motives explain how projects behave. Maintainers, the people who run a project, protect their time and the project's direction.

They welcome contributions that make both easier. Start by asking which project you already use and would like to improve.
