Learn LaTeX in 30 minutes

This tutorial gets you from zero to a working LaTeX document in about 30 minutes. You will create a document, add structure, format text, write equations, insert images, build tables, and finish with a practical next-step path.

​

What You Will Build

• A minimal LaTeX document that compiles cleanly
• A title block, sections, and basic text formatting
• Lists, equations, images, and tables
• A practical path into longer guides, templates, and project workflows

​

What is LaTeX?

LaTeX (pronounced “LAH-tek” or “LAY-tek”) is a document preparation system that produces professional-quality documents. Unlike word processors where you see the final result as you type, LaTeX uses plain text files with markup commands that get compiled into beautiful documents.

​

Why use LaTeX?

Think of LaTeX like HTML for documents. You write structured text, and LaTeX handles all the formatting consistently and professionally. It’s especially powerful for:

• Academic papers and theses
• Mathematical and scientific documents
• Books and long-form content
• Professional reports and presentations

​

Your First LaTeX Document

Let’s dive right in! Here’s the simplest possible LaTeX document:

​

Understanding the Structure

Every LaTeX document has two main parts:

1. Preamble (before \begin{document}): Document settings and package imports
2. Body (between \begin{document} and \end{document}): Your actual content

​

Adding Title and Author

Let’s make our document more professional by adding metadata: The \maketitle command creates a nicely formatted title block using the information you provided in the preamble.

​

Text Formatting

LaTeX provides simple commands for text formatting:

​

Paragraphs and Line Breaks

• Leave a blank line to start a new paragraph
• Use \\ to force a line break within a paragraph
• Use \newpage to start a new page

​

Creating Lists

LaTeX makes it easy to create both bullet points and numbered lists:

​

Adding Math Equations

This is where LaTeX truly shines! You can add math inline with $...$ or as display equations with \[...\]:

​

Inserting Images

To add images to your document, you’ll need the graphicx package:

​

Image Positioning Options

• [h] - here (approximately)
• [t] - top of page
• [b] - bottom of page
• [p] - separate page for floats

​

Creating Tables

Tables in LaTeX are powerful but need a bit of practice:

​

Table Column Alignment

• l - left aligned
• c - centered
• r - right aligned
• | - vertical line

​

Document Structure

For longer documents, use sections to organize your content: The \tableofcontents command automatically generates a table of contents based on your sections!

​

Comments in LaTeX

Use % to add comments that won’t appear in the output:

​

Common Packages

Extend LaTeX’s functionality with packages. Here are essential ones:

​

Troubleshooting Common Errors

​

Missing $ inserted

Problem: Math mode content outside math mode
Solution: Wrap math symbols in $...$

​

Undefined control sequence

Problem: Misspelled command or missing package
Solution: Check spelling and load required packages

​

Missing \begin

Problem: Content before document begins
Solution: Move content after \begin{document}
