+## Getting Started
+
+Fluid Python SDK provides two types of "client SDK" for users with different expertises and preference.
+- `fluid.FluidClient` (the recommended one) provides a more Pythonic interface with polished user experience.
+- `fluid.FluidK8sClient` provides a low-level YAML-style interface for those who have rich experience in Kubernetes.
+
+The following shows the same code example using two types of client SDK. The example simply creates a dataset and get its status.
