Operating System: The Atlassian SDK is available for various operating systems. In Jiradev.com, I have only provided examples for installation and development on Windows 8. The installation procedure for all operating systems are very well documented on the Atlassian Developer site. You should easily be able to install the SDK using the guides provided by Atlassian.
Do you have a Jira plugin tutorial that can be used on this site? Please do share it with me and I can add it along with the ones available.
Your feedback can help improve the content on this site. If you have anything that you would like me to change/implement on the site.
