 UPM (Useful Packages & Modules) Sensor/Actuator repository for MRAA
 ==============
 
-UPM is a high level repository for sensors that use MRAA. Each sensor links
-to MRAA and are not meant to be interlinked although some groups of sensors
-may be. Each sensor contains a header which allows to interface with it.
-Typically a sensor is represented as a class and instantiated.
+The UPM repository provides software drivers for a wide variety of commonly
+used sensors and actuators. These software drivers interact with the
+underlying hardware platform (or microcontroller), as well as with the attached
+sensors, through calls to [MRAA](github.com/intel-iot-devkit/mraa) APIs.
 
-The constructor is expected to initialise the sensor and parameters may be used
-to provide identification/pin location on the board.
+Programmers can access the interfaces for each sensor by including the sensor’s
+corresponding header file and instantiating the associated sensor class. In the
+typical use case, a constructor initializes the sensor based on parameters that
+identify the sensor, the I/O protocol used and the pin location of the sensor.
 
-Typically an update() function will be called in order to get new data from the
-sensor in order to reduce load when doing multiple reads to sensor data.
+C++ interfaces have been defined for the following sensor/actuator types, but
+they are subject to change:
+
+* Light controller 
+* Light sensor
+* Temperature sensor
+* Humidity sensor
+* Pressure sensor
+* Gas sensor
+* Analog to digital converter
+
+The developer community is encouraged to help expand the list of supported
+sensors and actuators and provide feedback on interface design.

+compatibility between releases:
+
+ * Our **C++ header files** changed their extension from *.h* to *.hpp* in
+ version 0.7.0, Intel provided examples and code samples also reflect this
+ change but you will need to modify your `#include` directives in existing code
+ * **my9221**, **groveledbar** and **grovecircularled** are now all part of the
+ same library (my9221) and new functionality was added going to v.0.5.1
+ * **stepmotor** driver API was changed significantly from v.0.4.1 to v.0.5.0
+ * **eboled** library was greatly improved in version 0.4.0 and the `draw()`
+ function was removed in favor of a more complete GFX library implementation
