@zleap Hi Paul, I hope you don't mind if I hijack this post a bit to plug a similar tool (though it's not collaborative in the same way as Overleaf) called RMarkdown! It has nearly all the features of LaTeX (since it compiles to LaTeX as an intermediate file type) but works with R to allow for seamless integration of code, typesetting, and reproducible data analysis, via loading R-Scripts. It also gets rid of a lot of the annoying markup syntax (\begin{} etc.) in most typical use cases(though they are still usable if necessary).

For anybody who's a fan of LaTeX, I HEAVILY suggest looking at this tool, and similar ones for languages like Julia's Weave etc. In RMarkdown specifically, you can also mix multiple languages into a single RMarkdown file that runs analysis and compiles your document!

Here's a link to the documentation and overview of the tool, and I've also included a Github link to a thesis template I wrote a while back to make it much easier to automate the figure making and typesetting process, in case anybody is interested!
