-## Workflow
+## How to preview multiple PRs?
 
-### Overview
+1. Create a new branch from the `mult-pr-preview` branch.
 
-![image](https://user-images.githubusercontent.com/56986964/183846841-d8a0027d-21cf-4d73-970d-89df0e456102.png)
+    Note: the new branch name cannot be `preview/**`, `preview-cloud/**`, or `preview-operator/**`.
 
-### How Docs Staging Update Itself
+2. Configure the following files:
 
-#### 1. Trigger by event from Docs Source Repo
+    - `sync_mult_prs.sh`: Replace `{PR_NUMBER_x}` and `{release-x.y}` with the actual PR numbers and release version you want to preview.
+    - `preview-mult-pr.yml`: Set the schedule for automatic PR preview.
+    - `docs.json` (optional): Add a new entry for the release version you're previewing or update the existing configuration, such as the stable version.

+3. Set the new branch as the default branch for the repository.
 
-#### 2. Trigger by event manually
+4. Manually trigger the `preview-mult-pr.yml` workflow to preview the PRs and validate the configuration.
