+# Deploy An App Without Pushing An Empty Commit
+
+The [Vercel CLI](https://vercel.com/docs/cli) allows you to make updated
+deployments of an app right from the command line. Many providers require you
+to push a new commit to the main branch to trigger a deployment. If there are
+changes, you can trigger a deployment by pushing these. If there aren't
+changes, but you want to re-deploy what is already there, then you have to
+create an empty commit and push that.
+
+With the [Vercel CLI](https://vercel.com/docs/platform/deployments#vercel-cli),
+you can deploy and re-deploy the app without pushing commits.
+
+To trigger a preview deployment:
+
+```bash
+$ vercel
+```
+
+To trigger a production deployment:
+
+```bash
+$ vercel --prod
+```
