+1. In the "Pull Requests" list, click the pull request you'd like to add to the merge queue.
+1. Click **Add to merge queue** to add your pull request to the merge queue. This enables the default **Queue and merge in a group** option. Alternatively, you can:
+   - Add your pull request to the front of the queue by selecting the **Add to merge queue** drop down menu, and clicking **Jump the queue** (only available to repository maintainers and administrators).
+   - Directly merge your pull request by selecting the **Add to merge queue** drop down menu, and clicking **Directly merge** (only available to repository administrators).

+   {% tip %} 
+
+   **Tip:** The **Add to merge queue** button is only enabled once the pull request meets all the review/approval and status check requirements.
+
+   {% endtip %}
+2. Confirm you want to add the pull request to the merge queue by clicking **Confirm add to merge queue**.
+   {% data variables.product.product_name %} adds the pull request to the merge queue and will merge it for you.
+
+## Viewing the merge queue
+
+You can view the merge queue in various places on {% data variables.product.product_name %}.
+
+   - On the **Branches** page for the repository. We recommend you use this route if you don't have or don't know about a pull request already in the queue, and if you want to see what's in the queue. For more information, see "[Viewing branches in your repository](/repositories/configuring-branches-and-merges-in-your-repository/managing-branches-in-your-repository/viewing-branches-in-your-repository)."
