[Tex/LaTex] How to add a space at the beginning of each line

Question

I am a beginner with TeX. I am trying to put a few spaces at the beginning of the line. Or a tab, whatever would work. But whatever I try it just puts space on the first line.
My questions:
How do I add a space in each line
and is there a good cheat sheet for using TeX?

This is a text document and I am trying to add Verilog code to be shown in the final pdf version of the document.
So here is an example of the latex document:

There are several ways to code a mux. Here is an example below:

\textit{\qquad input wire [7:0]} a;  \\
\textit{\qquad input wire \textit[7:0]} b;  \\
\textit{\qquad input wire [2:0] s;}   \\
\textit{\qquad output wire [7:0] fab;}  

\textit{\qquad assign fab = s[0] ? b : a;}\\  

This code infers an 8bit 2:1 mux.

Answer 1

Since you're trying to typeset code, perhaps the listings package will be helpful. You can adjust the left margin using xleftmargin.

\documentclass{article}
\usepackage[parfill]{parskip}
\usepackage{listings}
\begin{document}
There are several ways to code a mux. Here is an example below:

\begin{lstlisting}[xleftmargin=1em]
input wire [7:0] a;
input wire [7:0] b;
input wire [2:0] s;
output wire [7:0] fab;
assign fab = s[0] ? b : a;
\end{lstlisting}
