+Should I Git Ignore or Commit Bower Assets?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Currently, you should probably *commit* the assets downloaded by Bower instead
+of adding the directory (e.g. ``web/assets/vendor``) to your ``.gitignore``
+file:
+
+.. code-block:: bash
+
+    git add web/assets/vendor
+
+Why? Unlike Composer, Bower currently does not have a "lock" feature, which
+means that there's no guarantee that running ``bower install`` on a different
+server will give you the *exact* assets that you have on other machines.
+For more details, read the article `Checking in fronte-end dependencies`_.
+
+But, it's very possible that Bower will add a lock feature in the future
