read text from textarea, modify text with ruby, and output modified text

I'm trying to create a simple sinatra app with one page containing a text area with a submit button underneath. Below that is another textarea that displays the modified text from the first textarea after the submit button is clicked.

Sinatra is new to me, so this is the best I can come up with so far:

CH.erb

<html>
<head>
    <title>CH</title>
</head>
<body>
    <div id="main">
        <form action="" method="post">
            <textarea id="orig" rows="25" cols="150"></textarea>
            <br /><br /><br />
            <button type="submit">Submit</button>
        </form>
        <br /><br /><br />
        <textarea id="result" rows="25" cols="150"></textarea>
    </div>
</body>
</html>

CH.rb

require 'sinatra'

get '/hi' do
  erb :CH
end

post '/hi' do
  # ????
end

Use this for your response route:

post '/hi' do
  @result = params['orig']
  erb :CH
end

and modify your view like so:

<textarea id="result" rows="25" cols="150"><%=@result%></textarea>

I personally advocate Haml over Erb, but to each his/her own.
