How to build a crowd plugin?

[Ashley]

I'm relatively new to building plugins and I need some guidance on how to move forward on editing my Crowd based plugin. I've already set up my environment and downloaded the Atlassian SDK, but now I am just a bit lost on what to do next to modify my plugin towards how I want it to be like. I created a REST API plugin module for it and now I am unsure of how I can configure it or where I should be making changes to it. I've seen a lot of documentation on Jira plugins, but not for Crowd. Any insight would be greatly appreciated! (My plugin is for acquiring data from the Crowd database regarding the users so would REST API even be the right plugin module to go for?) I get that each plugin module is for each function, but how do I even start to tackle it? What is the process of implementing these changes to the plugin?
