Uploading MLS feed to my IDX template

I’m a realtor and I’m trying to update my website with my local realtor board MLS feed so people can go to my website and find properties that are available for sale.
I’m hosting with Bluehost and I’ve installed the template but properties aren’t being automatically uploaded onto my site.

Can someone please help me sort this out? Thank you!

Check the theme documentation or contact the developer/author. That will tell you how to install demo data
