 ## Ghidra Server
 
-For documenting the original binaries and generating pseudocode that we decompile with, we primarily use [Ghidra](https://ghidra-sre.org/) (it's free and open source). To help with collaboration, we have a shared Ghidra repository with all of our current work. You are free to check it out and mess around with it locally, however to prevent sabotage, you will need to request permission before you can push back to the server (ask in the Matrix room).

+## General Guidelines
+
+If you have contributions, feel free to create a pull request! Someone will review and merge it (or provide feedback) as soon as possible.
+
+Please keep your pull requests small and understandable; you may be able to shoot ahead and make a lot of progress in a short amount of time, but this is a collaborative project, so you must allow others to catch up and follow along. Large pull requests become significantly more unwieldy to review, and as such make it exponentially more likely for a mistake or error to go undetected. They also make it harder to merge other pull requests because the more files you modify, the more likely it is for a merge conflict to occur. A general guideline is to keep submissions limited to one class at a time. Sometimes two or more classes may be too interlinked for this to be feasible, so this is not a hard rule, however if your PR is starting to modify more than 10 or so files, it's probably getting too big.

+This repository currently has only one goal: accuracy to the original executables. We are byte/instruction matching as much as possible, which means the priority is making the original compiler (MSVC 4.20) produce code that matches the original game. As such, modernizations and bug fixes will probably be rejected for the time being.

 ## Code Style
 
 In general, we're not exhaustively strict about coding style, but there are some preferable guidelines to follow that have been adopted from what we know about the original codebase:

-## Kinds of Contributions
-
-This repository has only one goal: accuracy to the original executables. As such, we are not likely to accept pull requests that attempt to modernize the code, or improve compatibility in a newer compiler that ends up reducing compatibility in MSVC 4.20. Essentially, accuracy is king, everything else is secondary. For modernizations and enhancements, it's recommended to create a fork downstream from this one instead.
