Refined is set up a bit differently, depending on which Jira solution(s) you have installed.
When you combine have installed Refined (version 2.0 and newer) on an instance with Jira Service Management, your Help Center from native JSM is replaced by a Global JSM site. This site can’t be removed and holds all your JSM projects. You can also add projects from Jira Core and/or Jira Software by clicking the + Plus icon > Include Jira projects.
Aside form the Global JSM site, you can add as many additional sites as you want by clicking the Add site button in the Site Builder. You can then drag and drop projects away from the Global JSM site into the additional sites, or add them by clicking the + Plus icon > Include Jira projects.
When you combine have installed Refined on an instance with only Jira Core and/or Jira Software, there is no global site. You have to manually create one or more Refined sites, and add projects to them by clicking the + Plus icon > Include Jira projects.

Add structure to your sites by organising your Jira projects into categories and subcategories. Since Refined version 3.0, you can also add custom links to your site’s navigation.
