To produce a visible, typeset document, your LaTeX file is processed by a piece of software called a TeX engine which uses the commands embedded in your text file to guide and control the typesetting process, converting the LaTeX commands and document text into a professionally typeset PDF file. LaTeX works very differently: instead, your document is a plain text file interspersed with LaTeX commands used to express the desired (typeset) results. However, LaTeX’s mode of operation is quite different to many other document-production applications you may have used, such as Microsoft Word or LibreOffice Writer: those “ WYSIWYG” tools provide users with an interactive page into which they type and edit their text and apply various forms of styling. L aT eX (pronounced “ LAY-tek” or “ LAH-tek”) is a tool for typesetting professional-looking documents. 15.3 Packages available on Overleaf: Introducing TeX Live.15.2 Finding information about packages: CTAN.5 Including title, author and date information.
