 [Apache Mesos](http://mesos.apache.org) is now a Top-Level [Apache](http://www.apache.org) project, and we've moved the codebase. The [downloads page](http://mesos.apache.org/downloads) explains the essential information, but here's the scoop:
 
 Please check out the source code from Apache's git repostory:
-  
+
     git clone https://git-wip-us.apache.org/repos/asf/mesos.git
 
 or if you prefer GitHub, use the [GitHub mirror](https://github.com/apache/mesos):
 
     git clone git://github.com/apache/mesos.git
 
-For issue tracking and patches, we use Apache-maintained infrastructure including the [JIRA issue tracker](https://issues.apache.org/jira/browse/MESOS) instead of the GitHub one, and [review board](hreviews.apache.org) for patches instead of pull requests.
