+local Kubernetes clusters using Docker containers as nodes. It provides
+a fast and straightforward way to run Kubernetes for development and
+testing tasks.
+
+Supporting multi-node cluster configurations, kind is ideal for testing
+more complex, real-world scenarios without demanding extensive resources.
+It’s a lightweight, portable, and configurable solution useful in
+continuous integration (CI) workflows.")
