+Laggy distros
+=============
+For those running pop-culture distros that don't yet ship ``python3.6``
+you'll need to install it as well as `kivy source build`_ dependencies
+since currently there's reliance on an async development branch.
+
+For `ubuntu` this looks like::
+
+    sudo add-apt-repository ppa:jonathonf/python-3.6
+    sudo apt-get update
+    sudo apt-get install -y \
+        build-essential \
+        python3.6 \
+        python3.6-dev \
