Some of the best practices for open source software are:
License: Open source software should have a clear and appropriate license that defines the terms and conditions of the use, modification, or distribution of the products, and that protects the rights and interests of the developers, users, or contributors of the products.
Documentation: Open source software should have comprehensive and accessible documentation that explains the purpose, features, functionality, or requirements of the products, and that guides the users, contributors, or developers of the products.
Community: Open source software should have an active and inclusive community that supports, collaborates, or communicates with the users, contributors, or developers of the products, and that fosters a culture of openness, respect, or diversity.
