+This Mercurial hook updates a Jira bug with mercurial commits.  It utilizes Jira CLI and is triggered by Mercurial commits. 
+
+I wrote this hook so my mercurial commits would appear in a bug by putting my bug number into the comments.
+
+Dependencies
+============
+jira cli 2.6.0 
+ - https://marketplace.atlassian.com/plugins/org.swift.jira.cli#versions
+ - jira.sh needs to be accessible to your path 
+
+Installation
+============
+1. If $HOME/.hgrc doesn't exist, you need to create this file.  You then need to add the following line your $HOME/.hgrc
+<.hgrc>
+[hooks]
+commit = ~/.hg/jira-commit.sh 
+</.hgrc>
+
+2. Create a jira-setting file in $HOME/.hg/jira-setting
+<jira-settings>
+# No space
+JIRA_HOST=(your mercurial host include port if necessary)
+JIRA_USERNAME=(your username)
+JIRA_PASSWORD=(your password)
+</jira-settings>
+
+TODO
+====
+Eventually, I will write a installation script that uses ruby brew or something to automate all these steps.
