+            <li>A scheduled auto-build slot (<code>autoBuild.times</code> entry) can carry its own
+                <code>buildCommand</code>, so a nightly slot runs a fuller check than the quick
+                on-commit builds of the same branch. Restart, retry, and the startup recovery repeat
+                a build with the command it originally ran.</li>
+            <li>A slot can also carry a <code>name</code> (e.g. <code>master@nightly</code>): its
+                builds then get their own row in the branches view, their own history and retention
+                pool, and their own permanent latest-green artifact link
+                (<code>/branches/master_nightly/…</code>) — the branch's regular builds no longer
+                displace the nightly build and its artifacts.</li>
