I'm new to Middleman and ruby in general.

I've installed Ruby
I've installed Middleman and the gems to get it running.

I need to use slim instead of the default template system.

So I installed the Slim gem. Slim's website only says that I need to require 'slim' in order to get it to work.

The middleman website says I only need add the template engine to the config.rb file, but it gives no examples...

For someone with no ruby background, this is no help.

I looked for several config.rb on git and they all have:

```
require 'slim'

```

And 

```
# Set slim-lang output style
Slim::Engine.set_default_options :pretty => true

# Set template languages
set :slim, :layout_engine => :slim

```

I added that to my config.rb file and created the layout.slim and the index.html.slim

When I refresh my local server I get: 

```
Not Found

`/' not found.

```

I have middleman installed with Boilerplace. I'm not sure if there are more files that I need to change, but I can't find any good resources online, which is odd.

Could anyone give me some direction as to what I'm missing?
