How to install

1. Close Factorio.
2. Go to your Factorio install folder.
3. Open the data folder.
4. Copy the base and core folders from this repo into your Factorio/data folder, and choose to overwrite existing files.
5. You're done!

Making your own changes

If, for example, you don't like the colours of the wires above, it is super easy to make your own unique colours:

1. Go to your Factorio install folder. Most graphic files are in Factorio/data/base/graphics/icons
2. Open the file in an image editor.
3. Change the hue using a Hue/Saturation slider to something that's distinct to you. That's all you really need to do.
