 # speedrect
-Quick key bindings and other tools for rectangle-mark-mode
+Quick key bindings and other tools for Emacs rectangle-mark-mode.
+
+SpeedRect is a small Emacs package that provides convenience "modal" key 
bindings and other tools while in `rectangle-mark-mode` (`C-x SPC`, by 
default).  
+
+## Features
+
+- Key bindings for basic rectangle functions open, insert string, kill, 
delete, delete whitespace, clear, copy, yank.
+- Restore the last saved rectangle position, or start a new rectangle from 
point. 
+- Calc grab and sum commands.
+- Column shift: slide a rectangle left or right, 1 or 5 columns at a time (or 
any number, with a prefix). 
+- A help page (hit `?`). 
+
+## Installation
+
+Just download, add to path, and arrange to `(require 'speedrect)`.  For users 
of `use-package`:
+
+```elisp
+(use-package speedrect
+  :load-path "~/code/emacs/speedrect") ; or wherever
+```
+
+## Usage
+
+Hit `?` to see the key bindings available.
+
+## Hints
+
+A rectangle is just a _region_ (point and mark), specially interpreted.  You 
can `C-x C-x` to switch point and mark for easy changes.
