 ## Try it out
 This IPFIX library can be used to build an exporter. Please check out the [exporter tests](https://github.com/vmware/go-ipfix/blob/main/pkg/exporter/process_test.go) to get an idea on how to build exporter on top of TCP and UDP transport protocols given a IPFIX collector.
 
+To deploy a standalone go-ipfix collector, which is used to decode and log the IPFIX records, you can use:
+```
+cd <directory containing this README file>/build/yamls
+kubectl apply -f ./ipfix-collector.yml
+```
 ## Build Registry
 To build the registry from [IANA registry](https://www.iana.org/assignments/ipfix/ipfix.xhtml) or [Antrea registry](pkg/registry/registry_antrea.csv), run following commands:
 ```
