@@ -23,7 +23,7 @@ A typical CL to the main Go repo usually wants builders starting with `gotip-`.
 Once you select the builds you would like to run, there are two ways to trigger the test runs:
 
 * **Blocking**: This is the recommended approach. Add the `Cq-Include-Trybots` git footer displayed in the dialog to the last paragraph of the commit message. Once a patch set with the updated commit message is uploaded, vote `Commit-Queue+1` as usual. The additional builds are treated just like the default TryBots: failures will block submission and send email notifications, and the builds will automatically run on subsequent patch set (as long as the `Cq-Include-Trybots` line remains). Note that the `Cq-Include-Trybots` git footer will not be used if it's not in the last paragraph of the commit message. That is, it must be **right next to the `Change-Id` line without empty lines** (see screenshot below).
-* **Advisory only**: Clicking the "Add" button will immediately start running the tests (even without a `Commit-Queue+1` vote). These are completely one-off advisory builds only. Status and results will appear in the "Check" section (seen screenshot below), but failing results will not block submission or send an email notification. These builds will not automatically run again when a new patch set is uploaded.
