A basic tutorial of Sinatra.

### Requirements

This tutorial assumes that you are using the Cloud9 IDE.

Find a partner and begin typing the following exercises. You should alternate who types and who explains the output.

#### Install the Sinatra Gem

Type the following command in the C9 terminal:

```

gem install sinatra

```

#### Write a Hello World Sinatra App

Create an empty Ruby workspace. In the root directory of your workspace, create a file ```app.rb```. Type the following content in the file:

```ruby

require "sinatra"

get "/" do

    "Hello, world!"

end

```

#### Start the App

Type the following command in C9 terminal:  

**Note:** Type the following content literally, do not replace anything.

```

ruby app.rb -p $PORT -o $IP

```

#### Try Your App

In your browser, type the following URL to try your first Sinatra app:

```

http://-.c9users.io

```

Replace `````` and `````` with your C9 root directory name and your C9 username respectively. For example, my url is:  ```https://test-sinatra-jacksongl.c9users.io/```.

#### Exercise:

Add another page to your site with URL ```http://..c9.io/about```.

The page should display content: ```My name is .```
