+`vim-literate-coffeescript` adds syntax highlighting and indentation support for
+[Literate CoffeeScript](http://coffeescript.org/#literate) to the vim text
+editor.
+
+It looks something like this:
+
+![Preview](test/test.png)
+
+# Dependencies
+
+You must have syntax highlighting installed for both
+[Markdown](https://github.com/tpope/vim-markdown) and
+[CoffeeScript](https://github.com/kchmck/vim-coffee-script) installed to use
+this package.
+
+# Installation
+
+## Manually
+
+ 1. Clone this repository.
+
+        git clone https://github.com/mintplant/vim-literate-coffeescript.git
+
+ 2. Copy all the vim-specific files into your ~/.vim folder.
+
+        cp -r vim-literate-coffeescript/ftdetect/ ~/.vim/
+        cp -r vim-literate-coffeescript/indent/ ~/.vim/
+        cp -r vim-literate-coffeescript/syntax/ ~/.vim/
+
+## With Pathogen
+
+### Setup
+
+ 1. Install [Pathogen](http://www.vim.org/scripts/script.php?script_id=2332)
+
+ 2. Change directory to your bundle folder.
+
+        cd ~/.vim/bundle
+
+ 3. Clone this repository.
+
+         git clone https://github.com/mintplant/vim-literate-coffeescript.git
+
+### Updating
+
+ 1. Change directory to where the repository was cloned.
+
+        cd ~/.vim/bundle/vim-literate-coffeescript/
+
+ 2. Pull in the latest changes.

+The **Scope** class regulates lexical scoping within CoffeeScript. As you
+generate code, you create a tree of scopes in the same shape as the nested
+function bodies. Each scope knows about the variables declared within it,
+and has a reference to its parent enclosing scope. In this way, we know which
+variables are new and need to be declared with `var`, and which are shared
+with external scopes.
