Help:How to import articles
There is an article you have written and you would like to import it into Wikipedia? There are several ways to accomplish this.
The most obvious thing to do is to copy and paste content. Note, however, that most formatting will not be preserved. Also note that single linebreaks are ignored by Wikipedia, so if your source uses them, you will get very long linebreaks. If you know about regular expressions, you can use something like s/\n/<br>\n/gs to acomplish single linebreaks, or s/\n/\n\n/gs to replace them with full paragraphs.
If you want to properly import articles, you may consider using a conversion utility. David Wheeler has written such a program for converting HTML to Wikipedia, see the html2wikipedia homepage. If you do not manage to install and operate this program, just ask on this article's talk page, and someone may be able to help you getting your files imported. If your article is not in HTML, there are in most cases ways to convert it into that format.
If it is a very long article, and intended primarily for reference purposes, you can upload it as a file (link to it using the [[Media:Filename]] syntax. Since Wikipedia is not intended as an archive for source material, this should be used sparingly.
