+PlanToPI
+########
+
+A PM2.5 project using PlanTower sensors connected to a RaspberryPI board
+
+
+Architecture
+============
+
+The data flow from Plantower sensor to reliable API end point is broken down as follow:
+
+* Plantower sensor generates air quality data
+* RaspberryPI fetches data via serial port
+* Robust python code packs data and post to API end point
+
+Configuration
+=============
+
+
+Install
+=======
+
+First we need to install setuptools with:
+
+.. code:: sh
+
+    $ pip install -U setuptools pip
+
+To compile requirements use:
+
+.. code:: sh
+
+    $pip-compile --output-file requirements.txt requirements.in
+
+Install the requirements via:
+
+.. code:: sh
+
+    $ pip install -r requirements.txt
+
+Development
+===========
+
+
+Test
