-Introduction
-------------
-
-CMS, or Contest Management System, is a distributed system for running
-and (to some extent) organizing a programming contest.
-
-CMS has been designed to be general and to handle many different types
-of contests, tasks, scorings, etc. Nonetheless, CMS has been
-explicitly build to be used in the 2012 International Olympiad in
-Informatics, held in September 2012 in Italy.

-
-Download
---------
-
-**For end-users it's best to download the latest stable version of CMS,
-which can be found already packaged at .**
-
-This git repository, which contains the development version in its
-master branch, is intended for developers and everyone interested in
-contributing or just curious to see how the code works and wanting to
-hack on it.
-
-Please note that since the sandbox is contained in a [git submodule]
-(http://git-scm.com/docs/git-submodule) you should append `--recursive`
-to the standard `git clone` command to obtain it. Or, if you have
-already cloned CMS, simply run the following command from inside the
-repository:
-
-```bash
-git submodule update --init
-```
-
-
-Support
--------
-
-The complete CMS documentation is at .
-
-The mailing list for announcements, user support and general discussion
-is . You can subscribe at
-. So far, it is an extremely
-low traffic mailing list.
-
-The mailing list for development discussion (to submit feedback,
-proposals and critics, get opinions and reviews, etc.) is
-. You can subscribe at
-.
-
-**Please don't use these mailing lists for bug reports. File them on
-[github](https://github.com/cms-dev/cms/issues) instead.**
-
-For extemporaneous support and discussion, join the Gitter chat (see
-link above).
-
-To help with the troubleshooting, you can collect the complete log
-files that are placed in /var/local/log/cms/ (if CMS was running
-installed) or in ./log (if it was running from the local copy).
-
-
-Testimonials
-------------

-find an updated list at .
-
-If you used CMS for a contest, selection, or a similar event, and want
-to publicize this information, we would be more than happy to hear
-from you and add it to that list.
