# Verifier

The Verifier is an **exercise checker in the Editor which surfaces issues as you build**, helping you avoid last minute configuration-mismatches before publishing and running exercises.

## In the Editor

You'll find the Verifier in the top right-hand corner of your Editor next to *Designing for...* and `Run Exercise`.

Click on the :bell: bell icon to see suggestions/errors. In this example, the designer is being urged to check:&#x20;

* Social graph for MicroBlog
* Facilitator Dashboard settings (Reports) in Configuration

The Verifier will direct you to the correct place in the Editor to rectify the issue e.g. `Go to personas area` , while also giving you the option to `Ignore` should you wish to:

Once issues are rectified, they are automatically cleared from the Verifier panel. In this example, reports have been enabled:

### Before publishing

Before publishing, you can run a final check using the Verifier to catch any remaining issues. After selecting `Run exercise`, find the Verifier in the *Publish your exercise* window:

This helps to ensure your exercise runs as intended for both players and Facilitators.
