+VIC is Open Source software. This means that the code is made available for free, but also that development, maintenance and support need to be community efforts. Our rationale for moving the VIC model development to the open source community is that we want:

+## Support
 
-The VIC development community assumes the role of a limited scope of official support.
+There is no official support for the VIC model, other than the VIC documentation, the VIC source code archive and the description of the model in the literature. Any additional support relies on volunteer efforts by the  VIC development community, which means that no one is being paid to provide VIC support. The following resources are available:
 
-- Coordination of model development, bug fixes, and releases.
-- Distribution of model [documentation](http://vic.readthedocs.org) and [source code](https://github.com/UW-Hydro/VIC).

-Due to limited resources, there is not official support for some of the tasks related to using VIC.  We expected that the user comes prepared with some understanding of the model and scientific computing.  As such, these items are specifically not supported by the VIC development community:

 #### Requesting New features
 
-The VIC model is under active development.  If you would like to propose a new feature, driver, or extension to the VIC model, please raise a Github issue [here](https://github.com/UW-Hydro/VIC/issues). Also, because VIC is an open source model with little official support, please also be prepared to contribute to the implementation of your feature request.

Also, because VIC is an open source model with no official support for development, be prepared to contribute to the implementation of your feature request. Also note that features that are only of interest to you are unlikely to be implemented in the main source code repo (although you are of course free to modify the code in any way you see fit).
