 As a contributor, if you want to make any contribution to Kruise project, we should reach an agreement on the version of tools used in the development environment.
 Here are some dependents with specific version:
 
-- Golang : v1.13+ (1.15 is best)
+- Golang : v1.15+ (1.17 is best)
 - Kubernetes: v1.16+
 
 ### Developing guide
 
 There's a `Makefile` in the root folder which describes the options to build and install. Here are some common ones:
 
 ```bash
+# Generate code and manifests e.g. CRD, RBAC YAML files etc
+make manifests
+
 # Build the controller manager binary
 make build
 
 # Run the unit tests
 make test

+# Bump Kubernetes version
+
+## Preparing: Compatibility matrix
+
+| kubebuilder | controller-runtime | Kubernetes  |
+|-------------|--------------------|-------------|
+| 1.x         | 0.1.x              | 1.13        |
+| 2.x         | 0.2.x ~ 0.6.x      | 1.14 ~ 1.18 |
+| 3.x         | 0.7.x ~ ?          | 1.19 ~ ?    |
+
+Which means the correspondence between controller-runtime and Kubernetes:
+
+- controller-runtime v0.7  - Kubernetes v1.19
+- controller-runtime v0.8  - Kubernetes v1.20
+- controller-runtime v0.9  - Kubernetes v1.21
+- controller-runtime v0.10 - Kubernetes v1.22
+- ...
+
+So, you should firstly make sure your local kubebuilder is 3.x,
+and make clear which versions of Kubernetes and controller-runtime you are going to update.
+
+Usually we bump them every two versions with the even minor version, such as Kubernetes 1.20, 1.22.
+
+## Actions
+
+### Step 1: update dependencies in go.mod
+
+- Bump `k8s.io/kubernetes` to `v1.x.y`.
+- Bump `k8s.io/xxx` in require and replace to `v0.x.y`, except `k8s.io/kube-openapi` and `k8s.io/utils`, you can ignore them for now.
+- Bump `sigs.k8s.io/controller-runtime` to matched version with Kubernetes.
+
+Tidy them and download:
+
+```shell
+$ go mod tidy
+
+$ go mod vendor
+```
+
+### Step 2: solve incompatible problems
+
+Build and test:
+
+```shell
+$ make build test
+```
+
+Solve all incompatible problems in the project.
+
+### Step 3: fetch upstream changes of StatefulSet and DaemonSet
+
+We hope the Advanced StatefulSet and Advanced DaemonSet in Kruise should be compatible with the upstream ones.
+So you should look for the upstream changes and fetch them into Kruise.
+
+This can be done in next individual PRs to make this bump-version-PR more clear and readable.

 ### Second Step: Deploy your kruise with a deployment
-The followings are the steps to debug Kruise controller manager locally using Pod. Note that the
-`WEBHOOK_HOST` env variable should be unset if you have tried [above](#way-2-debug-your-kruise-locally)
-debugging methodology before.
-#### 1.Build controller-manager and CRDs
-Make your own code changes and validate the build by running `make build` and `make manifests` in Kruise directory.
-#### 2.Deploy customized controller manager
-The deployment can be done by following steps assuming a fresh environment.
-Note that the new controller manager will be deployed via a `Deployment` to replace the default Kruise controller manager.
-- Prerequisites: create new/use existing [dock hub](https://hub.docker.com/) account ($DOCKERID), and create a `kruise` repository in it;
-- step 1: `docker login` with the $DOCKERID account;
-- step 2: `export IMG=<image_name>` to specify the target image name. e.g., `export IMG=$DOCKERID/kruise:test`;
-- step 3: `make docker-build` to build the image locally;
-- step 4: `make docker-push` to push the image to dock hub under the `kruise` repository;
-- step 5: `export KUBECONFIG=<your_k8s_config>` to specify the k8s cluster config. e.g., `export KUBECONFIG=$~/.kube/config`;
-- step 6: `make deploy IMG=${IMG}` to deploy your kruise-controller-manager to the k8s cluster;
+#### 1. Generate code and manifests in your branch
+Make your own code changes and validate the build by running `make generate manifests` in Kruise directory.
+#### 2. Deploy customized controller manager
+The deployment can be done by following steps.
+- Prerequisites: prepare a `kruise` repository in an image registry, it can be [docker hub](https://hub.docker.com/) or your private hub.
+- step 1: `export IMG=<image_name>` to specify the target image name. e.g., `export IMG=$DOCKERID/kruise:test`;
+- step 2: `make docker-build` to build the image locally and `make docker-push` to push the image to registry;
+- step 3: `export KUBECONFIG=<your_k8s_config>` to specify the k8s cluster config. e.g., `export KUBECONFIG=$~/.kube/config`;
+- step 4:
+  - 4.1: `make deploy` to deploy Kruise to the k8s cluster with the `IMG` you have packaged, if the cluster has not installed Kruise or has installed via `make deploy`;
+  - 4.2: if the cluster has installed Kruise via helm chart, we suggest you just update your `IMG` into it with `kubectl set image -n kruise-system deployment kruise-controller-manager manager=${IMG}`;
 
 Tips:
-- If you need to update `mutatingwebhookconfiguration` or `validatingwebhookconfiguration` of kruise, please run `./scripts/uninstall.sh` in Kruise directory to uninstall them `before step 6`.
+- You have to run `./scripts/uninstall.sh` to uninstall Kruise if you installed it using `make deploy`.
 
 #### 3.View logs of your kruise
 You can perform manual tests and use `kubectl logs -n kruise-system <kruise-controller-manager-pod-name>` to check controller logs for debugging, and you can see your `<kruise-controller-manager-pod-name>` by applying `kubectl get pod -n kruise-system`.

 Kubebuilder default `make run` does not work for webhooks since its scaffolding code starts webhook server
 using kubernetes service and the service usually does not work in local dev environment.
