+    <h3>Automatic development builds</h3>
+    <p>
+        Automatic builds (sometimes called "nightlies") are generated at
+        regular intervals by our Continuous Integration process. This
+        allows to run the last version of our code, though it also means
+        you will get possibly very unstable work-in-progress, just as it
+        is made. Therefore ⚠️  <strong>be aware that you would be running
+        very experimental code!</strong> ⚠️
+        These builds are meant to test future GIMP versions and help us
+        debug, we do not advise to use these for production.
