To write a simple document without very much math, you don't have to do anything special; and you certainly don't need the \text macro.
\documentclass[a4paper,10pt]{article}
%% Uncomment the following line to use an AMSmath equation
%\usepackage{amsmath}
\title{A simple document consisting mostly of text}
\author{Niel de Beaudrap}
\begin{document}
\maketitle
\section{A section title}
The following is a simple displayed un-numbered equation.
\[
E = mc^2
\]
%% Uncomment the following as desired.
% In many cases, it's useful to use an equation environment
% from the AMSmath package. The following is a simple example
% which gives the displayed equation a number:
%\begin{equation}
% \mathbf{F} := \frac{\mathrm{d}}{\mathrm{d}t} \mathbf{p}
%\end{equation}
You can write as much prose as you want outside of the math environments
you use (indeed, you don't have to use \emph{any} math environments if
you don't want to).
\end{document}
Give that a try. You might want to investigate some simple introductory references for LaTeX, if you're starting from scratch.
\text. (The\textmacro is mostly for when you want to do things such as insert a little bit of prose into some mathematics.) – Niel de Beaudrap Apr 19 '13 at 15:49\textis for formatting text in math mode (you could use\mboxinstead if you don't need it to get smaller in subscripts) but do you need text in math at all? – David Carlisle Apr 19 '13 at 15:49
