+#### Start tidb-operator locally and do manual tests
+
+We uses [kind](https://kind.sigs.k8s.io/docs/user/quick-start/#installation) to
+start a Kubernetes cluster locally and
+[kubectl](https://kubernetes.io/docs/reference/kubectl/overview/) must be
+installed to access Kubernetes cluster.
+
+You can refer to their official references to install them on your machine, or
+run the following command to install them into our local binary directory:
+`output/bin`.
+
+```
+$ hack/install-up-operator.sh -i
+$ export PATH=$(pwd)/output/bin:$PATH
+```
+
+Make sure they are installed correctly:
+
+```
+$ kind --version
+...
+$ kubectl version --client
+...
+```
+
+Create a Kubernetes cluster with `kind`:
+
+```
+$ kind create cluster
+```
+
+Build and run tidb-operator:
+
+```
+$ ./hack/local-up-operator.sh
+```
+
+Start a basic TiDB cluster:
+
+```
+$ kubectl apply -f examples/basic/tidb-cluster.yaml
+```
+
 #### Run unit tests
 
 Before running your code in a real Kubernetes cluster, make sure it passes all unit tests.
