 ## Somewhere to save your files (required)
 
-Programming projects are normally made up of several related files, and we hope you'll come back to Codebar several times! You should create a folder on your hard drive dedicated to Codebar. Create a new folder inside it when you start work on a new tutorial.

-We recommend you use **[Atom](https://atom.io/)** at Codebar. It's free, open source, and runs on Windows, Mac, and Linux. **[Sublime Text 2](http://www.sublimetext.com/)** is another popular choice.
