Understanding UIF Registration for New Employees

I've recently started a small business and am in the process of hiring my first few employees. I know that registering for the Unemployment Insurance Fund (UIF) is a crucial step, but I'm not entirely sure of the specific requirements and process. Can someone walk me through the steps needed to register my new employees for UIF?

Are there any documents or information I need to have on hand? Additionally, what are the deadlines I need to be aware of to ensure compliance? Any advice or detailed guidance would be incredibly helpful!
