  Other than that, it is really simple to work out. I am happy to demonstrate it later when we meet. This format is really useful for writing particularly long documents, and for our collaborations. It is not as intrusive as using google docs where two people can work on the same piece of text and texts get changed constantly. Instead, here you can concentrate on the section where you want to work, and merge changes later. These change merging occurs at a different level, so there's not much of a worry.   ## How to insert Citations  I have included a few screenshots that shows you how to add citations to the text you are writing. In general, if you use BibteX, that's fine, but if not, just follow the steps. You can also use Endnote to add your citations. In general, you click on the plus sign above, and then add citation by either directly from the bibtex file or by searching the pubmed files.
