Registry Containers Configure on a Project


I’m trying to get container registry enabled, or installed but having issues, following this link below:

So I checked under the project settings > Integrations but the option isn’t there to enable, tick.

Looks like I need to add the module on the main gitlab, but I don’t just want to install it, is there any giuelines I can follow because I know gitlab needs tot be administrated carefully.

Any help would be appreciated.
