+## Testimonials
+
+The Gerrit community has a high interest in the users of the Gerrit Code Review
+project. We want to understand who our users are, why they like Gerrit and how
+Gerrit is integrated with their workflows. If your project or company is using
+Gerrit, we would like to know about your use case, so that we are aware of it
+when we evolve Gerrit further. If you use Gerrit, we kindly ask you to share
+your usage as a testimonial below.
+
+### How to add a testimonial?
+
+Upload a change to the
+[homepage](https://gerrit-review.googlesource.com/admin/repos/homepage) project
+that adds your testimonial to this page. If you don't know how to do this, just
+send an email to the
+[repo-discuss](https://groups.google.com/forum/#!forum/repo-discuss)
+mailing list that has a subject starting with '[testimonial]' and a Gerrit
+maintainer will take care to upload it for you.
