Success path for enable developer portal

Hi everyone, i’m not expert, a few months ago i installed and configure tyk on a server, for now is running and works nice but i want to make some apis public, I had reviewed the documentation but only says how to create and add an api to catalog. Before of that i need to enable the developer portal. Anyone know how to enable the portal?, I need to add some special configuration in config files?

This is my dashboard tyk configuration

Hi. It’s very simple - but you need to publish an API to the portal first - guide is here:
