 This repository contains a selection of packages mirroring the CircuitPython API
 on hosts running micropython. Working code exists to emulate the CircuitPython packages;
 
 * **board** - breakout-specific pin identities
 * **microcontroller** - chip-specific pin identities
+* **analogio** - analog input/output pins, using pin identities from board+microcontroller packages
 * **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
+* **pulseio** - contains classes that provide access to basic pulse IO (PWM)
 
+For details, see the `Blinka API reference
+<https://circuitpython.readthedocs.io/projects/blinka/en/latest/index.html>`_.
 
 Dependencies

+are running CPython or 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.
 
+Installing from PyPI
+=====================
+
+On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
+PyPI <https://pypi.org/project/Adafruit-Blinka/>`_. To install for current user:
+
+.. code-block:: shell
+
+    pip3 install Adafruit-Blinka
+
+To install system-wide (this may be required in some cases):
+
+.. code-block:: shell
+
+    sudo pip3 install Adafruit-Blinka
+
+To install in a virtual environment in your current project:
+
+.. code-block:: shell
+
+    mkdir project-name && cd project-name
+    python3 -m venv .env
+    source .env/bin/activate
+    pip3 install Adafruit-Blinka
