INSTRUCTIONS FOR LINUX
To set up with Ren'Py, download Renpy - for best results, use Ren'Py 8.1.3 (this has not been tested on more recent builds). Then, in the terminal:
Clone this repo into the same directory you saved RenPy to: git clone https://github.com/hobg0blin/dataville.git
Move into the Ren'Py launch directory: cd renpy-8.1.3-sdk/
Start Ren'Py: bash renpy.sh
For other OSes, you should be able to download and directly launch the sdk - instructions here
