Where is English language file?

I’m trying to change some words around but I can’t find en_us in Languages so I’m taking another language translator file and rewording that but I have to copy and paste over the prior tranlsation.

Is there an en_us file somewhere that I can just use?

The english texts are hardcoded in the PHP files, and the base for all other languages.

But you can overwrite them with this plugin: https://github.com/BlueTeck/kanboard_plugin_overwrite_translation
