LaTeX is a powerful typesetting system widely used for creating well-formatted, professional-quality documents. From academic papers to resumes, LaTeX can handle a variety of document types with precision. In this blog, we'll explore the basics of LaTeX and demonstrate how to create a CV. Additionally, we'll highlight how the same LaTeX packages can be used for different types of documents.

What is LaTeX?
LaTeX is a typesetting system that allows you to control the layout and formatting of your documents through plain text commands. Unlike traditional word processors, LaTeX separates content from formatting, enabling precise control over document appearance. It's particularly popular for academic writing, technical reports, and professional resumes.

LaTeX Basics: A Simple CV Example
Let’s start with a basic LaTeX code example for a CV:

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{geometry}
\geometry{top=1in, bottom=1in, left=1in, right=1in}
\usepackage{graphicx}
\usepackage{fancyhdr}
\usepackage{lipsum} % For dummy text
\usepackage[hidelinks]{hyperref} % For hyperlinks

% Set up header and footer
\pagestyle{fancy}
\fancyhf{}
\fancyhead[L]{\textbf{Your Name}}
\fancyhead[R]{CV}
\fancyfoot[C]{Page \thepage}

\begin{document}

\begin{center}
\includegraphics[width=0.2\textwidth]{profile.jpg} % Add your profile picture here
\end{center}

\begin{center}
\textbf{\Huge Your Name} \\
\textit{City, Country} \\
\textit{Date of Birth: DD\textsuperscript{th} Month YYYY} \\
\textit{\href{mailto:your.email@example.com}{your.email@example.com}} | \textit{(+Country Code)-Phone Number} | \textit{\href{https://www.linkedin.com/in/yourprofile}{LinkedIn}} | \textit{\href{https://github.com/yourprofile}{GitHub}}
\end{center}
