-;;; term-switcher.el --- Easily switch between open X11 terminals

 ;; Author: Vincent Ambo <tazjin@google.com>
-;; Version: 1.0
+;; Version: 1.1
 ;; Package-Requires: (dash ivy s)
 ;;
 ;;; Commentary:
 ;;
 ;; This package adds a function that lets users quickly switch between
-;; different open X11 terminals using ivy.
-;;
-;; It is primarily intended to be used by EXWM users who use graphical
-;; terminals inside of Emacs.
-;;
-;; Users MUST configure the group `term-switcher' and can then bind
-;; `ts/switch-to-terminal' to an appropriate key.
+;; different open vterms via ivy.
