+### HyperV Socket Support
+
+WinSocat is also allow to interact with hyper-v socket. It requires the vmId and serviceId to connect. For example, you can use this
+
+```
+winsocat stdio hvsock:0cb41c0b-fd26-4a41-8370-dccb048e216e:00000ac9-facb-11e6-bd58-64006a7986d3
+```
+
+to connect the VSOCK socket opened by WSL2 program. This program is running under the HyperV-VM with vmId `0cb41c0b-fd26-4a41-8370-dccb048e216e`. 
+And it opens the VSOCK port 2761(the hex format is 0x00000ac9). According to [hyper-v on windows](https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/make-integration-service),
+the VSOCK port on Linux will be equivalent to the serviceId `[port in hex]-facb-11e6-bd58-64006a7986d3` on windows. Hence, WinSocat provide the short representation for VSOCK.
+
+```
+winsocat stdio hvsock:0cb41c0b-fd26-4a41-8370-dccb048e216e:vsock-2761
+```
+
+This `vsock-2761` will be viewed as the serviceId `00000ac9-facb-11e6-bd58-64006a7986d3`.
