Sample config files: [.gitchangelog.rc](/gitchangelog/.gitchangelog.rc) and [template.tpl](/gitchangelog/template.tpl).
 
 `.gitchangelog.rc` sample is heavily commented and should be enough to make modification but for specific details you can refer to the original [repository](https://github.com/vaab/gitchangelog).
 The default template `markdown.tpl` is configured to create Markdown divided into sections (New, Changes, Fix, Others) based on the commits. The data sent to the output engine [pystache](https://github.com/defunkt/pystache) by the gitchangelog is in the following [format](https://github.com/vaab/gitchangelog/edit/master/README.rst#L331-L356). You can use it to create a custom template, please refer [mustache](http://mustache.github.io/).
