In this video we'll briefly explain the technology screen in which you can upgrade the technical prowess of your armies.
Factions can research technologies over time. These bring a variety of civic and military benefits. To start research into a technology, open up the technology panel by clicking on the technology button in the bottom right panel. Only one technology can be researched at a time, and each lead to other technologies on this panel, much like a tree. Hover over a technology to reveal its tooltip to learn what benefits it will provide; some technology research options also unlock after the construction of specific buildings.
