+⚠ This package is a work in progress
+
+`xterm-headless` is a headless terminal that can be run in node.js. This is useful in combination with the frontend [`xterm`](https://www.npmjs.com/package/xterm) for example to keep track of a terminal's state on a remote server where the process is hosted.
