+# Emacs Haskell Unicode input method
+
+This package provides **haskell-unicode-input-method**, an input
+method which allows you to easily type a number of Unicode symbols
+that are useful when writing Haskell code.
+
+To automically load in haskell-mode put the following code in your
+.emacs file:
+
+    (require 'haskell-unicode-input-method)
+    (add-hook 'haskell-mode-hook 
+      (lambda () (set-input-method "haskell-unicode")))
+
+Make sure the directory containing the .el file is in your load-path,
+for example:
+
+    (add-to-list 'load-path "~/.elisp/emacs-haskell-unicode-input-method")
+
+To manually enable use **M-x set-input-method** or **C-x RET C-\\**
+with **haskell-unicode**. Note that the elisp file must be evaluated
+for this to work.
+
+Now you can simply type `->` and it is immediately replaced with
+`→`. Use **C-\\** to toggle the input method. To see a table of all
+key sequences use** M-x describe-input-method haskell-unicode**. A
+sequence like `<=` is ambiguous and can mean either `⇐` or `≤`. Typing
+it presents you with a choice. Type 1 or 2 to select an option or keep
+typing to use the default option.
+
+If you don't like the highlighting of partially matching tokens you
+can turn it off:
+
+    (setq input-method-highlight-flag nil)
