 This guide assumes the following basics:
 * you have a working installation of Voldy's Web UI set ui
 * you already have the furry/yiffy models downloaded
-* you have node.js installed (**!**TODO**!** Port script to python, as everyone should have python already)
 
 You can also extend this into any other booru-oriented model, but you'll have to modify the pre-processing script according to the site images were pulled from. The general concepts still apply.

 ## Pre-Processing Script
 
-**!**TODO**!**: actually test the script, and port it to Python
-
-Below is a quick hack job from my server of the script. You're required to already have node.js and `node-fetch` version 2.x (`npm install node-fetch@2` in the folder with the script). It is ***imperative*** you install version 2, as later versions moved to needing `import` (YUCK) over `require`.
-
 You are not required to actually run this, as this script is just a shortcut to manually renaming files and curating the tags, but it cuts the bulk work of it.
 
+Included in the repo under [`./utils/renamer/`](https://git.coom.tech/mrq/stable-diffusion-utils/src/branch/master/utils/renamer) is a script for tagging images from e621 in the filename for later user in the web UI.
+
+For little additional configuration, use the python variant: `preprocess.py` (credits to [anon](https://boards.4chan.org/trash/thread/51463059#p51472156)). Just put your images in the `./utils/renamer/in/` folder, then run the script.
+
+You can also have multiple variations of the same images, as it's useful if you're splitting an image into multiple parts. For example, the following is valid:
+```

+554982d3498e67a50f768e6e18088072 (2).jpg
+```
+
 The generalized procedure is as followed:
 * load a list of tags associated with the SD model
 * grab a list of filenames
