+  Enables the ability to preview the deployment plan against a given commit before merging.
+---
+
+> NOTE: This feature is currently under Alpha status.
+
+In order to help developers review the pull request with a better experience and more confidence to approve it to trigger the actual deployments,
+PipeCD provides a way to preview the deployment plan of all updated applications by that pull request.
+
+Here are what will be included currently in the result of plan-preview process:
+
+- which application will be deployed once the pull request got merged
+- which deployment strategy (QUICK_SYNC or PIPELINE_SYNC) will be used
+- which resources will be added, deleted, or modified
+
+This feature will available for all application kinds: KUBERNETES, TERRAFORM, CLOUD_RUN, LAMBDA and Amazon ECS.

+PlanPreview with GitHub actions <a href="https://github.com/pipe-cd/actions-plan-preview">pipe-cd/actions-plan-preview</a>
+</p>
+
+## Prerequisites
+
+- Ensure the version of your Piped is at least `v0.11.0`.
+- Having an API key that has `READ_WRITE` role to authenticate with PipeCD's control-plane. A new key can be generated from `settings/api-key` page of your PipeCD web.
+
+## Usage
+
+Plan-preview result can be requested by using `pipectl` command-line tool as below:
+
+``` console
+pipectl plan-preview \
+  --address={ PIPECD_CONTROL_PLANE_ADDRESS } \
+  --api-key={ PIPECD_API_KEY } \
+  --repo-remote-url={ REPO_REMOTE_GIT_SSH_URL } \
+  --head-branch={ HEAD_BRANCH } \
+  --head-commit={ HEAD_COMMIT } \
+  --base-branch={ HEAD_BRANCH }
+```
+
+You can run it locally or integrate it to your CI system to run automatically when a new pull request is opened/updated. Use `--help` to see more options.
+
+``` console
+pipectl plan-preview --help
+```
+
+## GitHub Actions
+
+If you are using GitHub Actions, you can seamlessly integrate our prepared [actions-plan-preview](https://github.com/pipe-cd/actions-plan-preview) to your workflows. This automatically comments the plan-preview result on the pull request when it is opened or updated. You can also trigger to run plan-preview manually by leave a comment `/pipecd plan-preview` on the pull request.
