+        Below is a list of useful tools and data sets available only in the Zulip
+        development environment that are often useful when contributing to Zulip.
+        Most of these require you to run a command to build/generate the relevant
+        content. This table specifies which command to use to update the data served
+        by each page (since several of these, like test coverage, require a special
+        command to be run to generate the data). Make sure your development server is still running
+        when you visit these!
