You are invited to contribute to Couchbase open-source projects during Hacktoberfest. Explore various starter kits, including a new project called Couchbase Starter Kits, which provides a streamlined way to start building with Couchbase in your favorite language and framework. You can also dive into the Couchbase Shell, a powerful tool for interacting with Couchbase data in a fast, efficient, and flexible way. Additionally, you can explore VSCode and JetBrains extensions that provide seamless integration with Couchbase. The Couchbase Examples repository hosts numerous quickstart projects and tutorials that help developers get started with Couchbase, and you can contribute to this by suggesting new projects, improving existing examples, reviewing and testing them, or exploring open issues. Furthermore, you can get involved in the Couchbase Ecosystem projects by contributing to existing plugins, building new integrations, documentation, and examples, or checking out Couchbase Labs for experimental features and prototypes.
