# Automatic latexdiff on Overleaf

Upload all files in this directory to the top level of a new Overleaf project.
Set `texchanges-review.tex` as the Main document and use pdfLaTeX. Each
recompile runs `latexdiff` over `texchanges-original.tex` and
`texchanges-revised.tex`, then displays the generated visual diff.

Edit the two filenames in `latexmkrc` to match a real project. Keep filenames
free of shell metacharacters because they are part of a compile command.

To compile either revision without diffing, temporarily comment out the
`$pdflatex` line in `latexmkrc`, then select that revision as the Main document.

This workflow follows Overleaf's documented method:
