+# IPFS Cluster Follow Test
+
+This test verifies that the IPFS Cluster is capable of joining
+a collaborative cluster and replicating data.
+
+### Test Steps:
+
+- 00. Create an IPFSCluster resource
+- 05. Assert the CR is available
+- 10. Validate that the IPFS container is pinning the gutenurg_es CIDs

+# IPFSCluster Test
+
+This test validates that the operator is capable of creating the amount of required replicas,
+and that data can be made available and accessed through IPFS.
+
+### Test Steps:
+
+- 00. Assert the Operator is running
+- 05. Create an IPFSCluster resource
+- 10. Assert the desired amount of replicas were created
+- 15. Test creation on one replica and retrieval from another
