-TRMNL BYOS Laravel is a self-hostable implementation of a TRMNL server, built with Laravel.
+LaraPaper is a self-hostable implementation of a TRMNL server (BYOS), built with Laravel.
 It allows you to manage TRMNL devices, generate screens using **native plugins** (Screens API, Markup), **recipes** (130+ from the [OSS community catalog](https://bnussbau.github.io/trmnl-recipe-catalog/), 700+ from the [TRMNL catalog](https://trmnl.com/recipes), or your own), or the **API**, and can also act as a **proxy** for the native cloud service (Core). With over 50k downloads and 200+ stars, it’s the most popular community-driven BYOS.
