Does anyone have documentation for Sigma Replacements?

[Dankgum]

I've heard Sigma Replacements is a lot more easier to use and is more modular. However, there is no documentation or tutorials on how to use Sigma Replacements to replace the textures. I tried going on the forum thread, but he has now deleted all the info. If anyone has the documentation, it'd be greatly appreciated. Thanks!

I had to remove the old info because it was outdated.

I haven't had time to write new syntax guides, but if you open an issue on github I can help you with what you need
