 ## reMarkable 2 support
 
-The inputs are fully working on the reMarkable 2. The framebuffer is still a work in progress, however it can be run by using [this shim](https://github.com/ddvk/remarkable2-framebuffer#framebuffer-client-shim). The game may be a bit less performant with it as not all refresh modes are figured out, but it'll work.
+This app cant actually drive the rM 2 framebuffer. It needs [rm2fb](https://github.com/ddvk/remarkable2-framebuffer/) for that.
+
+If you execute retris from ssh, be sure to have followed rm2fb steps to enable the support. When launching through a launcher (from toltec) it should just work but have more ghosting on the rM2.
