+# Contributing
+
+If you want to contribute to KoboldKare, first you'll want to make an issue describing the thing you want to change.
+A moderator should respond to help collaborate and contribute to making the change happen.
+
+After that, in order to contribute to KoboldKare, you just need to do the following:
+- Fork the project.
+- Make the change.
+- Submit a pull request.
+
+You can read more about how this is done here: https://docs.github.com/en/get-started/quickstart/fork-a-repo
+
+# Installing and Editing KoboldKare
+
+1. Install git. If you're on modern windows, you can use the `winget` package manager for this:
+   ![winget example image](winget_install.png)
+   Just install it by typing `winget install Git.Git` into a powershell or cmd.
+2. Install blender. Funnily enough this is *also* in the windows package manager. You can install it with `winget install BlenderFoundation.Blender`.
+3. Install UnityHub, winget has this available as: `winget install UnityTechnologies.UnityHub`
+4. Download the KoboldKare's version of Unity. As of this commit it is 2021.3.6f1, which you can download by putting this link into a browser: [unityhub://2021.3.6f1/7da38d85baf6](unityhub://2021.3.6f1/7da38d85baf6)
+5. Restart the computer. This is important if you've just installed git. As you need to make sure the git executable is in your path **before** you try to open the project.
+6. Clone the KoboldKare repository. This can be done with something like Github Desktop. You'll want to clone *your* fork of KoboldKare, so that you'll have access to push commits.
+7. Open the KoboldKare folder with UnityHub. It should now import correctly!
+
+This is all you need to do to open, edit, and test KoboldKare.
+
+# Building
+
+You do not need to build KoboldKare to make changes, though to prevent questions-- here's how to build KoboldKare when you get to it.
+You first need to build addressables.
+You can find instructions on that here: https://docs.unity3d.com/Packages/[email protected]/manual/Builds.html
+
+After that you can build normally (File->Build Settings->Build). Do not run the KoboldKare continuous integration builders found in the KoboldKare->Build menus.
