+### Worker Node Requirements
+
+Your Amazon EKS cluster must include at least one worker node to host the Palette agent, which is essential for Palette
+to manage the cluster. Due to EKS architectural constraints, the Palette agent cannot be installed on the EKS control
+plane.

+- **Minimum Instance Type**: Worker nodes must use an instance type of at least **t3.xlarge** to ensure adequate
+  resources. AWS sets a default storage of 20 GB for Linux-based EKS worker nodes (the

+  parameter), and we recommend this as the minimum size.

+- **Ongoing Node Availability**: To maintain continuous management capabilities, at least one worker node should remain
+  available at all times for the Palette agent to operate effectively.

 ### Disable OIDC Associate Provider
 
 You can disable the OIDC associate provider if the service provider restricts the cluster deployment with the OIDC
