# filecontents Package in LaTeX

> Generate auxiliary files such as .bib files directly from your LaTeX source using filecontents.

`filecontents` is useful for self-contained examples and reproducible templates.

\begin{filecontents*}{references.bib}
@article{smith2024,
  author={Smith, John},
  title={Example Article},
  journal={Journal of Examples},
  year={2024}
}
\end{filecontents*}

\documentclass{article}
\usepackage[backend=biber,style=authoryear]{biblatex}
\addbibresource{references.bib}

See \parencite{smith2024}.
