I’m trying to write my first very basic plugins on Discourse, after read a lot about Ruby and the benefits the language offers to us 🙂

I want to add text to specific pages like badges, leaderboard (gamification) and similar simple edits like changing the default behavior on search order results, last posts instead relevance.

I understand the best approach is avoid forking the core and write plugins. So where can I look if I want to change specific files on Discourse from a plugin?

We can take an example editing this file:

_How to tell Discourse to use the plugin `topic_embed.rb` and replace default one?_
