-Description
-===========
-
 This repository contains a selection of packages mirroring the CircuitPython API
-on hosts running micropython. At the time of writing drafts exist for
+on hosts running micropython. Working code exists to emulate the CircuitPython packages;
 
-* board - breakout-specific pin identities
-* microcontroller - chip-specific pin identities
-* digitalio - digital input/output pins, using pin identities from board/microcontroller
+* **board** - breakout-specific pin identities
+* **microcontroller** - chip-specific pin identities
+* **digitalio** - digital input/output pins, using pin identities from board+microcontroller packages
+* **bitbangio** - software-driven interfaces for I2C, SPI
+* **busio** - hardware-driven interfaces for I2C, SPI, UART
+* **time** * - substitute functions monkey-patched to time module
 
 
 Dependencies
 =============
 
-The CircuitPython compatibility layers described above are intended for devices which
-are running Micropython. Given the top level packages should be provided by any standard
-CircuitPython image, you shouldn't be trying to put those packages on any board
-with CircuitPython already installed.
-
-However, the test suites under testing.implementation.all are by design
-intended to run on either CircuitPython or the Micropython+compatibility layer, so that
-conformance can be achieved.
-
-Similarly the test suites under testing.implementation.micropython should only be run
-on Micropython and testing.implementation.circuitpython should only be run on CircuitPython
+The Micropython compatibility layers described above are intended to provide a CircuitPython-like API for devices which
+are running Micropython. Since corresponding packages should be built-in to any standard
+CircuitPython image, they have no value on a device already running CircuitPython and would likely conflict in unhappy ways.
 
+The test suites in the test/src folder under **testing.universal** are by design
+intended to run on *either* CircuitPython *or* Micropython+compatibility layer to prove conformance. 
 
 Usage Example
 =============
 
-At the time of writing `git:3b2fc268 <https://github.com/cefn/Adafruit_Micropython_Blinka/tree/3b2fc268d89aee6a648da456224e6d48d2476baa>`,
-the following sequence runs through some basic testing of the digitalio compatibility layer.
+At the time of writing (`git:7fc1f8ab <https://github.com/cefn/Adafruit_Micropython_Blinka/tree/7fc1f8ab477124628a5afebbf6826005955805f9>`_),
+the following sequence runs through some basic testing of the digitalio compatibility layer... 
 
 .. code-block:: python
 
-    import testing
-    testing.main()
+    from testing import test_module_name
+    test_module_name("testing.universal.digitalio")
+
+An example log from running the suites is `here <https://github.com/cefn/Adafruit_Micropython_Blinka/issues/2#issuecomment-366713394>`_ .
