Getting Started with Compact Machines

Two items are all you need:

1. Craft a Compact Machine of the size you want. Each machine is built from a room template (see Room Templates & Sizes) - the template decides how big the room inside will be. If no templates are available on your world yet, an operator can enable the built-in set with one command (see below).
2. Craft the Personal Shrinking Device (PSD). This handheld device is your door into every room.
3. Place the machine block anywhere in the world. Its distinctive black-and-white casing with a green core marks the entrance.
4. Use the PSD on the placed machine - you are shrunk and teleported inside, into a sealed room made of machine walls, ready to build in.
5. Build anything inside - machines, farms, storage, even more Compact Machines.
6. Use the PSD on a room wall to step back outside, right where the machine block sits.
