Open Source
What is open source?
The term "open source" refers to something people can modify and share because its design is publicly accessible.
The term originated in the context of software development to designate a specific approach to creating computer programs. Open source projects, products, or initiatives embrace and celebrate principles of open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community-oriented development.
