Make an XCode project into a downloadable disk image

I have an XCode project that I want to get onto the internet so others can download it. I was wondering how I can turn my app into a disk image or something so that it can be put onto my website and other can then download it. Thanks in advance.

I would just use a zip file (or something similar). In Finder, right-click (or control-click) your application and choose Create Archive.
