-Slate turns a markdown file into a beautiful API documentation page for your service.
+Slate turns a markdown file into a beautiful API documentation page for your service. Think of it as a documentation template on steroids.
 
-This is much easier to show rather than explain, so as an example please see [TripIt's API Documentation page](http://tripit.github.io/docs), which we generated with Slate. You can also view the source of the [markdown file used to generate it](http://github.com/tripit/docs/blob/master/source/index.md).
+Slate puts all your API's descriptions and definitions on left half of the screen, and all your code examples on the right half. Inspired by [Stripe's](https://stripe.com/docs/api) and [Paypal's](https://developer.paypal.com/webapps/developer/docs/api/) API docs.
+
+If you have API bindings in multiple programming languages, you can easily make tabs at the top of the page to switch the code examples between those languages.
+
+As an example, you can check out our [API docs](http://tripit.github.io/docs), which we create with Slate. You can also view the source of the [markdown file used to generate it](http://github.com/tripit/docs/blob/master/source/index.md).

 ### Making Edits
 
-Just edit the markdown file `source/index.md`! Super easy. Here's an example of some markdown:
-
-    # This is a Major Section Header
-    
-    This is a bunch of text that will appear in the light-background section to the left of your docs.
-    
-    ## This is a Header of One of Your API Endpoints
-    
-    Blah blah blah blah blah blah blah
-    
-    ## Another Endpoint Header
-    
-    More text here. This all appears in the area on the left.
-    
-    ### This is a Subheader (won't appear in the table of contents)
-    
-    ```ruby
-    # this is a ruby code block that will appear in the dark area on the right
-    def say_hello
-      puts "hello"
-    end
-    ```
-    
-    ```python
-    // this is a python code block that will appear in the dark area on the right
-    print "hello, world"
-    ```
-    
-    ```shell
-    # this is a shell code block that will appear in the dark area on the right
-    echo "hello, world"
-    ```
-    
-    ```
-    This is a generic text block that will appear in the dark area on the right
-    ```
-    
-    > This is a code annotation that will appear in the dark area on the right
-    
-    This is [an internal link to one of the headers above](#another-endpoint-header).

-    This | Is  | A   | Table
-    ---- | --- | --- | -----
