+Blender Cloud Addon
+===================
+
+Congratulations on downloading the Blender Cloud addon. For your
+convenience, we have bundled it with the Blender ID addon.
+
+To use the Blender Cloud addon, perform the following steps:
+
+- Use Blender (File, User Preferences, Addons, Install from file)
+  to install blender_id-x.x.x.addon.zip
+
+- If you had a previous version of the Blender Cloud addon installed,
+  restart Blender now.
+
+- Log in with your Blender ID.
+
+- Use Blender to install blender_cloud-x.x.x.addon.zip
+
+    If you don't see the addon in the list, enable the Testing
+    category.
+
+- Press Ctrl+Alt+Shift+A to start the texture browser.
+
+- Visit the User Preferences, Addons panel, to use the Blender Sync
+  feature.
+
+
+Support for Blenders not from blender.org
+-----------------------------------------
+
+Maybe you use Blender from another source than blender.org, such as an
+Ubuntu package. If that is the case, you have to make sure that the
+Python package "requests" is installed. On Ubuntu Linux this can be
+done with the command
+
+    sudo apt-get install python3-requests
+
+On other platforms & distributions this might be different.
+
+Blender uses Python 3.5, so make sure you install the package for the
+correct version of Python.
+
+
+Subscribing to the Blender Cloud
+--------------------------------
+
+The Blender Sync feature is free to use for everybody with a Blender
+ID account. In order to use the Texture Browser you need to have a
+Blender Cloud subscription. If you didn't subscribe yet, go to:
+
+    https://cloud.blender.org/join
+
