First of all, critically evaluate your product to see if it can really be interesting to CodeProject members. Look at good number of other works, to get an idea. Package your code properly, complete with demo applications and code documentation. Make sure you don't include anything except real source code, without any build or revision control artifacts. Write an article explaining the purpose of your code, its usefulness, principles of its design, interesting programming techniques, compatibility and version information. Submit the article with ZIP-ed source code here:
