A: Hi,
Basically means that you would start by adding details like the appName, appDescription and the domainName in the config.ts . And then you would go to the seo.tsx in the /libs folder and adjust that one as well to fit your marketplace.
And once you have done that you can then import that one (import { getSEOTags } from "@/libs/seo";) on all your pages and that makes it a bit faster to add metaData to all your pages.

And also, on the ones you forget to import the metaData object to, then these pages will still have the default metaData information.
