+h3. Tell Workbench about the keep-web service
+
+Workbench has features like "download file from collection" and "show image" which work better if the content is served by keep-web rather than Workbench itself. We recommend using the two different hostnames ("download" and "collections" above) for file downloads and inline content respectively.
+
+Add the following entry to your Workbench configuration file (@/etc/arvados/workbench/application.yml@). This URL will be used for file downloads.
+
+<notextile>
+<pre><code>keep_web_download_url: https://download.<span class="userinput">uuid_prefix</span>.your.domain/c=%{uuid_or_pdh}
+</code></pre>
+</notextile>
+
+Additionally, add *one* of the following entries to your Workbench configuration file, depending on your DNS setup. This URL will be used to serve user content that can be displayed in the browser, like image previews and static HTML pages.
