Prison Architect Modding Guide
In its current form, Prison Architect is a fun game that doesn't offer a ton of long term play. The mods that I will show you will hopefully change that, allowing you to play a single prison for anywhere from 5 - 10 hours.

Mod Locations
Due to Prison Architect being in alpha, currently the modding scene is fractured and hard to keep up with. Hopefully that will change over time, but here are a few resources for game mods:
Both of the Prison Architect forums are pretty good resources for finding mods, although they aren't specifically set up for mods.
Prison Exchange is specifically set up for mods, but unfortunately does not have any up to date mods. The mods present at that site may or may not work on Alpha 8, but hopefully that will change in the future.
Great Mods and Maps
Installing Maps
Maps are save game files that people edit, then distribute to other players. Maps can be challenging scenarios or someone just showing off their newest prison. These are distributed as .PRISON files, and are loaded within the game by loading them just like any save game.

How to install on Windows Vista, 7 and 8:
Navigate to C:\Users\USERNAME\AppData\Local\Introversion\Prison Architect\saves Replace USERNAME with your Windows user name. Copy all files to that folder.
Installing Mods
Mods are files distributed by an author that add more grants, change the graphics, or modify high-level aspects of the gameplay mechanics.

Most mods are distributed with a readme.txt file. This file should always contain the most up to date instructions on how to install the mod. In the event a mod is distributed without a readme.txt, follow these instructions:

How to install on Windows Vista, 7, and 8:
Navigate to your Steam directory. Navigate to the \SteamApps\common\Prison Architect folder. Create a folder named data Copy any and all files into that folder.

Hey, when you subscribe to a mod on the workshop that is a map not a mod where can I find that file?

i think for a modding guide, a "How to" mod section is really needed, even getting the foundation such as where to start, what tools you need can be a great asset to future developers

Could you update this for Alpha 15 compatibility please?

Hey no worries, its not your fault there are currently issues with steams server causing the save feature to fail, but just to update your guide to mod the game all you need to do is open the main.dat file with your fav archiving application and extract the contents then you can edit the files as needed. I would help with your guide by going through the process but I'm currently writing my own guide and cause of the depth I'm going into its taking me longer than I expected but I'm sure you can take it from there.

Yeah, I know. I don't know if Steam Guides are just bugged or if I'm doing it wrong, but every time I change the name and click Next it just resets to the original one. I'll look into it further later.

Not really a modding guide more a guide to mods, maybe consider renaming it for the time being as you give no guide to actually modding the game at all beyond linking to the current resources and saying how to install mods that have been already made, beyond that this is useful info on how to install the mods available.
