+## How to contribute to CoffeeScript
+
+* Before you open a ticket or send a pull request, [search](https://github.com/jashkenas/coffee-script/issues) for previous discussions about the same feature or issue. Add to the earlier ticket if you find one.
+
+* Before sending a pull request for a feature, be sure to have [tests](https://github.com/jashkenas/coffee-script/tree/master/test).
+
+* Use the same coding style as the rest of the [codebase](https://github.com/jashkenas/coffee-script/tree/master/src). If you're just getting started with CoffeeScript, there's a nice [style guide](https://github.com/polarmobile/coffeescript-style-guide).
+
+* In your pull request, do not add documentation to `index.html` or re-build the minified `coffee-script.js` file. We'll do those things before cutting a new release.

+      Besides being used as an ordinary programming language, CoffeeScript may
+      also be written in "literate" mode. If you name your file with a
+      <tt>.litcoffee</tt> extension, you can write it as a Markdown document &mdash;
+      a document that also happens to be executable CoffeeScript code.
+    </p>
+
+    <p>
+      Just for kicks, a little bit of the compiler is currently implemented in this fashion:
+      See it
+      <a href="https://gist.github.com/jashkenas/3fc3c1a8b1009c00d9df">as a document</a>,

+    </p>
+
+    <p>
+      I'm fairly excited about this direction for the language, and am looking
+      forward to writing (and more importantly, reading) more programs in this style.
+      As <b>1.5.0</b> is the first version of CoffeeScript that supports it, let us know
+      if you have any ideas for improving the feature.

+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.
+
+Import the helpers we plan to use.
