+  shortDescription: Start a remote packet capture on pods using tcpdump and wireshark
+  caveats: |
+    This plugin needs the following programs:
+    * wireshark (optional, used for live capture)
+  description: |
+    When working with micro-services, many times it's very helpful to get a capture of the network
+    activity between your micro-service and it's dependencies.
+
+    ksniff use kubectl to upload a statically compiled tcpdump binary to your pod and redirecting it's
+    output to your local Wireshark for smooth network debugging experience.
