[?] What is NanoMC?

NanoMC is a portable, no-install build of Minecraft 1.8.9.
It packs everything into a folder less than 300MB, runs from anywhere, and doesn’t require Java or setup.
Remember, Eaglercraft is NOT native java, it's WebGL! This runs on native java x64!

Basically: grab it, plug in, double-click, and play. Perfect if you love quick PvP sessions on the go.
