Creating and configuring the Self Aplication Portal - BigFix 10.0.9.21

Hi, i’m trying to create/configure the Self Aplication Portal and the Catalog but i’m stuck with it.

I already configure the self application configuration file and some software with the proper icon that i can deploy via Offer.

But i want to create the self application portal with a catalog of software for people in my organization can sign in and choose which software they want to install.

Can anyone give me a direction how to do it??

Best regards

Raul
