-This package provides an @samp{orderless} @emph{completion style} that divides the
-pattern into space-separated components, and matches candidates that
-match all of the components in any order. Each component can match in
-any one of several ways: literally, as a regexp, as an initialism, in
-the flex style, or as multiple word prefixes. By default, regexp and
-initialism matches are enabled.
-
-A completion style is a back-end for completion and is used from a
-front-end that provides a completion UI@. Any completion style can be
-used with the default Emacs completion UI (sometimes called minibuffer
-tab completion) or with the built-in Icomplete package (which is
-similar to the more well-known Ido Mode). To use a completion style in
-this fashion simply add it as an entry in the variables
-@samp{completion-styles} and @samp{completion-category-overrides} (see their
-documentation).
-
-With a bit of effort, it might still be possible to use @samp{orderless} with
-other completion UIs, even if those UIs don't support the standard
-Emacs completion styles. Currently there is support for @uref{https://github.com/abo-abo/swiper, Ivy} and
-@uref{https://github.com/raxod502/selectrum, Selectrum} (see below).
-
-If you use MELPA, the easiest way to install @samp{orderless} is via
-@samp{package-install}. If you use both MELPA and @samp{use-package}, you can use:
-
-@lisp
-(use-package orderless
-  :ensure t
-  :init (icomplete-mode) ; optional but recommended!
-  :custom (completion-styles '(orderless)))
-@end lisp
-
-Alternatively, put @samp{orderless.el} somewhere on your @samp{load-path}, and use
-the following configuration:
-
-@lisp
-(require 'orderless)
-(setq completion-styles '(orderless))
-(icomplete-mode) ; optional but recommended!
-@end lisp
-
-(And of course, if you use another completion framework such as Ivy or
-Helm, disable it.)
-
-If you like the experience of using @samp{orderless} with Icomplete, but wish
-the candidates displayed vertically, you can use @uref{https://github.com/oantolin/icomplete-vertical, icomplete-vertical}.
-
-Bug reports are highly welcome and appreciated!
