Milestone Categories allow you to group Milestones together thematically, and filter by Category on the Milestones page.
Managing Milestone Categories
The Manage Categories button can be found on the Milestones page, in the Categories drop down menu.
Editing Milestone Categories
To edit a Milestone Category, click on the pencil icon next to the Category name. To delete a Milestone Category, click on the trash can icon (note that you can only delete a Category if all Milestones have been removed from it).

To create a new Category, click the Add Category button, then name your new Category and click Create Category.
To add a Milestone to your new Category (or to an existing Category), click on the '+' next the Category name, then select the Milestone from the drop down menu.
