+## VPP trace replat utility
+
+This utility allows you to replay API traces generated by VPP,
+while doing some pre-processing (e.g. creating network namespaces 
+before tap creation)
+
+To use, issue in VPP:
+```console
+vppctl# api trace save trace.cap
+```
+
+Then run the utility on the output
+```console
+# for json output use
+go run -file ./path/to/trace.cap
+# to replay in VPP use
+go run -file ./path/to/trace.cap -vpp /run/vpp/vpp.api.sock
+```
