We currently have 5 pre-made Language Localisation packs available thanks to our community. Simply click on one of the below links and paste the contents into your Initial Variable Values located in F3 Settings / Overlay.
You can create your own Localisation using the English:English pack (or from any other language). If you do create your own Localisation we would really appreciate if you could contribute to the community by sharing it with us! Please join our Discord server linked below to share.
