+### Dennis Evangelista
+This library provides mbed support for Spektrum serial receivers. 
+
+## Obtaining the library
+Source code is revision controlled using Git and hosted in a Github repository.
+```bash
+git clone ssh://git@github.com/devangel77b/spektrum.git
+git pull
+```
+The ```dev``` branch is bleeding edge; ```master``` branch is reasonably up to date. 
+
+## Using the library
+The main part of the library are two classes for Spektrum (receiver) and BindPlug, which allows binding a transmitter to the receiver. In addition, a convenience function for converting 0-2048 values to PwmOut pulsewidths (600-2100us, centered at 900us) is provided (```spektrum_us()```).
