Ruby on start page?

As stated, I am new to rails, and Runy for that matter. I am working on a simple project to get acquainted and wanted to use ruby code in index.html, I changed the name to .rhtml and added the following simple code:

<% link_to 'Artists', :action => 'list' %>

This works great in my view files, but in the index.rhtml file, not so much. The error is:

"uninitialized constant WelcomeController"

What should I be doing differently?

Thanks,

Mike

Are you advising dont use index.html at all? I got rid of the standard one and made my own but maybe that wont work. I have 3 tables with model, view, and controller files setup as needed. I just want a start page that allows me to summarize the tables (counts, etc.) and provide links into their views. Is it best to create some new object called "start"?

Thanks for quick response!
