 A (very experimental) plugin for the [Bevy](https://bevyengine.org) engine which allows for rendering to a terminal window.
 
 WARNING: I highly recommend using the kitty terminal emulator with this, not only due to the gpu-accelerated rendering, but also the implementation of the kitty protocol which enables the advanced input detection.
 
 Features Include:
-- `TerminalDisplayBundle` automatically sets up a correctly-formatted render texture
+- `TerminalDisplay` automatically sets up a correctly-formatted render texture
 - Post-process dithers colors to pure black and white, which are then printed as braille characters to the terminal
 - Responsiveness to terminal window resizing
 - `TerminalInput` resource which keeps track of pressed & released keys
