Introduction
Technical documentation requires precise formatting, clear structure, and professional appearance. LaTeX provides the capabilities needed to create comprehensive manuals, API documentation, and user guides.
This guide covers technical writing best practices in LaTeX.

API Documentation
Function Reference
\subsection{calculate()}
\begin{verbatim}
calculate(x, y)
\end{verbatim}
\textbf{Description:} Adds two numbers.
\textbf{Parameters:}
\begin{itemize}
\item \texttt{x} (number): First operand
\item \texttt{y} (number): Second operand
\end{itemize}
\textbf{Returns:} Sum of x and y
\textbf{Example:}
\begin{minted}{python}
