This article outlines some of the basics of layout in LaTeX.
Note: Rather than typing up all the examples, you can copy-paste the examples into your TeXnicCenter files. We highly recommend opening up your TeXnicCenter and trying out each of the examples as you go. It takes almost no time at all to just copy-paste, compile, and view the results.

Source File Format
The source file of a LaTeX broadly consists of two parts, the preamble and the document itself. The preamble consists of everything before the \begin{document} command. Things like margin settings, document style definitions, paragraph spacing settings, custom function definition and page numeration style are items that are set in the preamble. Often, much of the preamble is placed in a separate file and included using the \usepackage statement. This allows you to use the same code in many source files by just including a single line in each source file.
Our next three sections deal primarily with preamble items, while the rest cover tools you might use within your document.
Document Class
The first line of your source code sets the document class with the cleverly named command \documentclass. While LaTeX supports several classes, such as book, report, and letter, we will be focusing on the document class article in these webpages. Using \documentclass, we can also set the general font size for the document (which we can reset for parts of the document as required). Thus, the first line of your source code will almost always look like this:
\documentclass[11pt]{article}
If you want a slightly larger font, try 12pt. If smaller, go for 10pt.
Should you decide to use one of the other classes, for example if you chose to write a book with LaTeX, we suggest getting a book on LaTeX.
