Steps for doing latexdiff
- Download 2 versions from overleaf
- Compile them using the TexStudio. I should create a bbl file.
- Create a new tex file where you replace the bibliography section with the contents of the bbl file.
- Do the same for the other version of the file.
- Check that the new tex file for both version compiles to the same contents of the original tex files.
- Open https://3142.nl/latex-diff/ and paste the contents of the new tex files from both versions in the text boxes.
- Click the box named "Generate LateX document showing differences"
- It will take some time and then create the diff file.
