 When deploying and using PD microservices, pay attention to the following:
 
 - After you enable microservices and restart PD for a cluster, PD stops allocating TSO for the cluster. Therefore, you need to deploy the `tso` microservice in the cluster when you enable microservices.

-## Deploy PD microservices
-
-Starting from v8.0.0, PD supports the [microservice mode](/pd-microservices.md) (experimental). You can deploy the `tso` microservice and `scheduling` microservice for your cluster using TiUP Playground as follows:
-
-```shell
-tiup playground v8.0.0 --pd.mode ms --pd.api 3 --pd.tso 2 --pd.scheduling 3
-```
-
-- `--pd.mode`: setting it to `ms` means enabling the microservice mode for PD.
-- `--pd.api num`: specifies the number of APIs for PD microservices. It must be at least `1`.
-- `--pd.tso num`: specifies the number of instances to be deployed for the `tso` microservice.
-- `--pd.scheduling num`: specifies the number of instances to be deployed for the `scheduling` microservice.
