I’m trying to do something like [this](https://meta.discourse.org/t/redirect-on-click-user-avatar-and-username-to-user-profile-page-u-username-summary/263403) and have my dev environment, but i’m not familiar how to go about this?

Do i use this to create a new plugin for my site? or is it embedded into one of the files?

You don’t need to create a plugin for that anymore. You can do it in a theme component.

Maybe this will help: [https://github.com/pfaffman/discourse-custom-homepage-for-groups/blob/main/javascripts/discourse/initializers/custom-homepage-set.js.es6](https://github.com/pfaffman/discourse-custom-homepage-for-groups/blob/main/javascripts/discourse/initializers/custom-homepage-set.js.es6)
