+The build process of latexmk will create two folders for storing temporary cache files for faster rebuilds. The primary folder being `.tmp` which will hold every created .aux file. Additionally the resulting pdf file will be located besides main.tex as well as an index file called `main.synctex.gz` used for indexing between main.tex and main.pdf (unused by VSCode, used by Overleaf).
