+### Vercel
+
+Vercel is an all-in-one platform with Global CDN supporting static and JAMstack deployment and Serverless Functions. Connect your Sentry and Vercel projects to automatically upload source maps and notify Sentry of release deployment.
+
+**Installation**
+
+1. Visit <https://vercel.com/integrations/sentry/add>
+
+2. Select your account and click "Add".
+
+    ![Sentry modal showing Vercel installation](vercel_install.png)
+
+    **Note that the installation created an internal integration to generate an auth token used in building releases. If the Vercel internal integration is deleted, your Vercel integration will stop working!**
+
+    ![Sentry modal showing Vercel internal integration](vercel_internal_integration.png)
+
+**Project Linking**
+
+1. Select a Sentry project and a Vercel project to link together.
+
+    ![Sentry modal showing linking Sentry project to Vercel project](vercel_link_project.png)
+
+    * This step will generate environment variables in the selected Vercel project. Having these set means you can skip the [CLI Configuration step](https://github.com/getsentry/sentry-webpack-plugin#cli-configuration) in the Sentry Webpack Plugin setup. You can see these in Vercel in **Project Settings** > **General** > **Environment Variables**.
+
+    ![Sentry modal showing linking Sentry project to Vercel project](vercel_env_vars.png)
+
+    * `SENTRY_ORG` - the name of your Sentry organization
+    * `SENTRY_PROJECT` - the name of your linked Sentry project
+    * `SENTRY_AUTH_TOKEN` - the auth token from the Vercel Internal Integration that was created upon installation
+    * `NEXT_PUBLIC_SENTRY_DSN` - the linked Sentry project's DSN
+    * `VERCEL_GITHUB_COMMIT_SHA`, `VERCEL_GITLAB_COMMIT_SHA`, or `VERCEL_BITBUCKET_COMMIT_SHA` - your source code provider's commit SHA, used for creating releases and associating commits
+
+  2. Redeploy your Vercel project in order to trigger a release.
+
+**Usage**
+
+* If you have not already done so, [instrument your code with Sentry](/error-reporting/quickstart/).
+* Ensure you have [installed a repository integration](/workflow/releases/#install-repo-integration) and added the relevant repository.
+* Add the [Sentry Webpack Plugin](https://github.com/getsentry/sentry-webpack-plugin) to your configuration. For NextJS, use `next.config.js`.
+* If you already have a Vercel project integrated with Sentry, ensure the Sentry project you link is the one you're already using to report errors.
+
+**Uninstallation**
+
+1. The integration must be uninstalled from Vercel. Visit the Vercel integration configuration page (**Organization Settings** > **Integrations** > **Vercel** > **Configurations**) and click "Uninstall" then "Visit Vercel" in the modal that pops up. 
+
+    ![Sentry modal showing uninstalling Vercel integration](vercel_uninstall.png)
+
+2. Click "Remove Configuration"
+
+3. Delete the internal integration that was created by navigating to **Organization Settings** > **Developer Settings** and clicking the trash can icon next to **Vercel Internal Integration**. You will be prompted to confirm the deletion by entering a string provided in the modal. Enter the string and click "Confirm" to finalize the deletion.
