+# `@replit/ruspty` - PTY for Bun (and Node) through Rust FFI
+
+Running:
+
+- `bun install`
+- `bun run build`
+- `bun test`
+
+The code mainly targets Bun, but does work in Node too.
+
+The Rust PTY implementation is cargo-culted from [Alacritty's Unix TTY code](https://github.com/alacritty/alacritty/blob/master/alacritty_terminal/src/tty/unix.rs).

 The code mainly targets Bun, but does work in Node too.
 
+The biggest difference from existing PTY libraries is that this one works with Bun, and doesn't cross the FFI bridge for every input/output instead requiring the consumer to deal with the `fd` of the PTY.
+
 The Rust PTY implementation is cargo-culted from [Alacritty's Unix TTY code](https://github.com/alacritty/alacritty/blob/master/alacritty_terminal/src/tty/unix.rs).
