 `jenkins_tracker` is a command line utility packaged as a [RubyGem](https://rubygems.org) that integrates [Jenkins](http://jenkins-ci.org/) build information with
 the relevant [Pivotal Tracker](https://www.pivotaltracker.com) stories within a project.
 
-It's ideally run as a Post Build Action in Jenkins.

 This utility makes some very specific assumptions about your Jenkins environment:-
 
 * Git as your SCM via the [Jenkins Git Plugin](https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin).
 
 * The Jenkins build changelog file is available at `$JENKINS_HOME/jobs/$JOB_NAME/builds/$BUILD_NUMBER/changelog.xml`.
+  The changelog contents look like this [example](https://github.com/prashantrajan/jenkins_tracker/blob/master/spec/fixtures/git_changelog.txt).
 
-* Ability to execute Ruby scripts.
+* Ability to execute Ruby 1.9.x scripts.
 
+* Environment variables exists for `$JENKINS_HOME`, `$JOB_NAME`, `$BUILD_NUMBER` & `$BUILD_URL`.

 The following are required for your Pivotal Tracker project:-
 
 * [API access enabled](https://www.pivotaltracker.com/help/api) (enabled by default).
