Once you've used NCSA Mosaic for a while, you may want to create your own documents or home pages and make them available to the WWW. If you're familiar with a markup language, such as Tex, Latex, or troff, you'll make the transition to HTML (Hypertext Markup Language) readily.
You can write an HTML document with any text editor. Try the Source button of your browser (or save it as an HTML file) to look at the HTML for a page you find particularly interesting. The odds are that writing an HTML document will be a great deal simpler than you'd expect. If you're used to marking up text in any way, HTML should be intuitive.
A beginner's guide to HTML is available at the URL (universal resource locator) http:/www.n
csa.uiuc.edu/General/Internet/WWW/HTMLPrimer.html. You can also find a plain-text version (at the URL ftp://ftp.ncsa.uiuc.edu/ncsapubs/WWW/HTMLPrimer.txt) and a compressed PostScript version (at the URL ftp://ftp.ncsa.uiuc.edu/ncsapubs/WWW/HTMLPrimer .ps.Z). Because the latter two are FTP URLs, you can fetch them by hand using FTP if you do not yet have a WWW browser.
In addition, there is a good set of HTML documentation available at the URL http://www.ucc.ie/info/net/htm1doc.html, and there's an HTML primer with a URL of http://www.vuw.ac.nz/who/Nathan.Torkington/ideas/www-html.html.
Again, to learn the particulars, see the relevant on-line documentation.
