Overleaf is the perfect solution for anyone running a LaTeX training workshop—no need for any participant to install LaTeX: just bring a portable device equipped with a modern browser. Because Overleaf is a cloud-based LaTeX platform, it minimises support requirements and significantly reduces the organizers' workload—helping the event get off to a flying start.
One of our Advisors, Rodrigo Smarzaro, ran a workshop in May at Federal University of Viçosa, Brazil at Academic Week for the Information Systems Undergraduate Course. Here is a link to Rodrigo’s slides (they are in Portuguese). We also asked him a few questions about how it went and what was involved in setting it up.
