+=== Coordinated checkpointing of distributed applications ===
+'''Summary:''' Enable coordinated container checkpointing with Kubernetes.
+
+Checkpointing support has been recently introduced in Kubernetes, where the
+smallest deployable unit is a Pod (a group of containers). Kubernetes is often
+used to deploy applications that are distributed across multiple nodes.
+However, checkpointing such distributed applications requires a coordination
+mechanism to synchronize the checkpoint and restore operations. To address this
+challenge, we have developed a new tool called <code>criu-coordinator</code>
+that relies on the action-script functionality of CRIU to enable synchronization
+in distributed environments. This project aims to extend this tool to enable
+seamless integration with the checkpointing functionality of Kubernetes.
