library: first implementation of the Digi XBee C# Library

The original project has been split in two modules:

- XBeeLibrary.Core: contains all the common code for any platform.
- XBeeLibrary.Xamarin: contains the necessary APIs to develop
  cross-platform mobile applications with Xamarin to communicate with XBee
  devices over Bluetooth Low Energy.

+# How to Contribute
+
+## Getting help
+
+To ask questions about the XBee C# Library go to the 
+[Digi Forum](http://www.digi.com/support/forum).
+
+
+## Reporting a bug
+
+The way to report bugs is to use the 
+[GitHub issue tracker](http://github.com/digidotcom/xbee-csharp/issues).
+Before reporting a bug, please read the following points:
+
+1. Make sure that it is really a bug by checking the 
+[documentation](https://www.digi.com/resources/documentation/digidocs/90002359/).
+2. If you still think you have found a bug, make sure someone has not already
+reported it. See the list of 
+[known issues](http://github.com/digidotcom/xbee-csharp/issues).
+3. If it has not been reported yet, create a new issue. Make sure to add enough 
+detail so that the bug can be reproduced.
+
+**Note**: The issue tracker is for bugs, not requests for help. Questions 
+should be asked on the [Digi Forum](http://www.digi.com/support/forum) instead.
+
+
+## Suggesting a new feature
+
+1. Consult the [documentation](https://www.digi.com/resources/documentation/digidocs/90002359/) 
+to ensure that the behavior you would like is not excluded.
+2. Make sure someone has not already requested it. See the list of 
+[known issues](http://github.com/digidotcom/xbee-csharp/issues).
+3. Submit your request in the issue tracker.
+
+
+## Contributing code
+
+1. Fork the [XBee C# Library](http://github.com/digidotcom/xbee-csharp) 
+repository ([how to fork a repo](https://help.github.com/articles/fork-a-repo/)).
+2. Create a branch for your contribution. Use a name that defines the purpose of the additions/modifications. 
+3. Make your changes following the code style used in the library.
+4. Submit a pull request ([how to create a pull request](https://help.github.com/articles/fork-a-repo/#next-steps)).
+A project developer will review your work and then merge your request into the
+project, or come back to you with comments and/or questions.
