-;;; clipmenu.el --- Emacs client for clipmenu -*- lexical-binding: t -*-
-;; Author: William Carroll <wpcarro@gmail.com>

-;;; Commentary:
-;; Ivy integration with the excellent program, clipmenu.
-;;
-;; clipmenu is a simple clipboard manager xsel. Usually clipmenu integrates with
-;; dmenu.  This Emacs module integrates with ivy.  Launch this when you want to
-;; select a clip.
-;;
-;; The following environment variables allow you to customize clipmenu's
-;; behavior:
-;;
-;; - CM_DIR: specify the base directory to store the cache dir in
-;;   (default: $XDG_RUNTIME_DIR, $TMPDIR, or /tmp)
-;; - CM_HISTLENGTH: specify the number of lines to show in ivy. (default: 8)
-;;
-;; Other variables for customizing clipmenu are defined herein.
-;;
-;; For more information, see `clipmenu --help`.

-;; TODO: Support an ivy action of deleting an entry from clipmenu.

+;;; ivy-clipmenu.el --- Emacs client for clipmenu -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; Ivy integration with the clipboard manager, clipmenu.  Essentially, clipmenu
+;; turns your system clipboard into a list.
+;;
+;; To use this module, you must first install clipmenu and ensure that the
+;; clipmenud daemon is running.  Refer to the installation instructions at
+;; github.com/cdown/clipmenu for those details.
+;;
+;; This module intentionally does not define any keybindings since I'd prefer
+;; not to presume my users' preferences.  Personally, I use EXWM as my window
+;; manager, so I call `exwm-input-set-key' and map it to `ivy-clipmenu/copy'.
+;;
+;; Usually clipmenu integrates with rofi or dmenu.  This Emacs module integrates
+;; with ivy.  Launch this when you want to select a clip.
+;;
+;; Clipmenu itself supports a variety of environment variables that allow you to
+;; customize its behavior.  These variables are respected herein.  If you'd
+;; prefer to customize clipmenu's behavior from within Emacs, refer to the
+;; variables defined in this module.
+;;
+;; For more information:
+;; - See `clipmenu --help`.
+;; - Visit github.com/cdown/clipmenu.
