+## This is my personal project
+
+I make this project in my free time whenever I feel like it. I make no promises about reading issues or pull requests on a timely basis, or that I will fix certain issues or merge pull requests (soon or ever).
+
+If you are making a significant addition and you intend for it to be implemented in my repository, you should talk to me first, because putting it in my repo means I have to maintain it. Please keep in mind the above paragraph. Maybe keep your own fork if you need something.
+
+## No AI-generated content
+
+This project, like all my projects, employs a strict zero-tolarance policy against any content generated by artificial intelligence, for any reason. Do not use it for issues, pull requests, comments, or anything else. Any content found to be the result of generative AI will be deleted, and the user likely blocked.

 - Ubuntu/Debian: `sudo apt install python3-tk`
-- Manjaro/Arch: `sudo pacman -S tk`

-Install the requirements listed in "Summary", then run `ci-gui.py`.
 
 ## Development
 
 ### Building Windows standalone
 
-Using a 32-bit version of Python is recommended to build a version to be distributed.
+> [!WARNING]
-
+> This section is OUTDATED and currently does not work with the Python package setup.
-A [virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) is recommended to isolate the packages from system directories. The build script `make-standalone.bat` assumes that the dependencies are in PATH.
-
-Install the dependencies, plus cx-Freeze. In a virtual environment, the specific Python version doesn't need to be requested.
-```batch
-pip install cx-freeze -r requirements-win32.txt
-```
-
-Copy `custom-install-finalize.3dsx` to the project root, this will be copied to the build directory and included in the final archive.
-
-Run `make-standalone.bat`. This will run cxfreeze and make a standalone version at `dist\custom-install-standalone.zip`
