I need to edit the topics/show.html.erb file to add some custom functionality.
I have edited this locally and all works fine, but I would like to know if there is a better way to edit those files without them being rewritten at each upgrade.
Thanks.

You don’t want to do it that way. You need to develop a plugin (or perhaps theme component). See [Beginner’s Guide to Creating Discourse Plugins Part 1: Creating a basic plugin](https://meta.discourse.org/t/beginners-guide-to-creating-discourse-plugins-part-1-creating-a-basic-plugin/30515) and [Developer’s guide to Discourse Themes](https://meta.discourse.org/t/developer-s-guide-to-discourse-themes/93648).
