Basicinstallationguide?

Coming back to POI after a year or more, I can't remember how to begin. The "Getting Started" part of the documentation skips installation. I imagine this may be hurdle for beginners. Should we install globally? If so, what is the code to do so? Is it

? Is that the only step required before the "Getting Started" instructions work? Thanks.
