-Usage Example
-=============
+Installing from PyPI
+====================
 
-See examples/thermal_printer_simpletest.py for a demo of basic printer usage.
+On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
+PyPI <https://pypi.org/project/adafruit-circuitpython-thermal_printer/>`_. To install for current user:

-Sphinx documentation
------------------------

+
+    sudo pip3 install adafruit-circuitpython-thermal_printer
 
-Sphinx is used to build the documentation based on rST files and comments in the code. First,
-install dependencies (feel free to reuse the virtual environment from above):
+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
-    pip install Sphinx sphinx-rtd-theme

+Documentation
+=============
 
-This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to
-view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
-locally verify it will pass.
