what are open source projects
Open source projects provide tremendous opportunities for developers to share and learn through collaboration. Find colleagues for your project or join an existing effort. Contributions aren't limited to code, as projects need a diverse range of skills.
When an author contributes code to an open-source project (e.g., Apache.org) they do so under an explicit license (e.g., the Apache Contributor License Agreement) or an implicit license (e.g. the open-source license under which the project is already licensing code).
