 ## Publish/Unpublish your KubeSphere extension
 
 You can publish/unpublish KubeSphere extension to KubeSphere cluster once it's ready:
 
 ```shell
 ksbuilder publish/unpublish <extension-name>
 ```
+
+## Push and submit your extension to KubeSphere Cloud
+
+### Create API access token
+
+1. Register an account on [KubeSphere Cloud](https://kubesphere.cloud).
+2. Open [KubeSphere Marketplace](https://kubesphere.co/marketplace/), click on "Become a service provider," sign the agreement, and become an extension service provider (i.e., developer).
+3. Open [https://kubesphere.cloud/user/setting/](https://kubesphere.cloud/user/setting/), click on "Security," then click "Create Token," check "Extension Component," and click "Generate." The generated token is the cloud API key, formatted like `kck-xxx`. Please keep it safe.
+
+### Login to KubeSphere Cloud
+
+Use the `ksbuilder login` subcommand to login to KubeSphere Cloud:
+
+```
+$ ksbuilder login
+✔ Enter API token: ***
+
+Login Succeeded
+```
+
+or:
+
+```
+$ ksbuilder login -t xxx
+
+Login Succeeded
+```
+
+### Push and submit the extension
+
+Use the `ksbuilder push` subcommand to submit the plugin to KubeSphere Cloud. The `push` subcommand is similar to `publish` and the target can be either a directory or a packaged `.tgz` file:
+
+```
+$ ksbuilder push tower
+
+$ ksbuilder push tower-1.0.0.tgz
+```
+
+> NOTE: We will upload static files such as icons and screenshots in the extension to the KubeSphere Cloud separately
+and delete the static file directory in the original package to reduce the size of the entire chart.
+
+### Check the extension status
+
+After submitting the extension, it needs to be approved by an administrator before it can be listed on KubeSphere Marketplace. You can use the `ksbuilder get` or `ksbuilder list` subcommands to check the status of the extension:
+
+```
+$ ksbuilder list
+
+ID                   NAME                STATUS              LATEST VERSION

+482307830796264605   kubeblocks          ready               0.6.3
+```
+
+```
+$ ksbuilder get tower
