+  Two important notes:
+    * We've added `googleapiclient` as the primary suggested import
+      name, and kept `apiclient` as an alias, in order to have a more
+      appropriate import name. At some point, we will remove `apiclient`
+      as an alias.
+    * Due to an issue around in-place upgrades for Python packages,
+      it's not possible to do an upgrade from version 1.2 to 1.3. Instead,
+      setup.py attempts to detect this and prevents it. Simply remove
+      the previous version and reinstall to fix this.
