Getting started
At this point Unator isn't planned to be published as a library in NuGet. So basically whenever you want to use certaian module/feaute you just copy file, that contains this feature from GitHub.
In the docs for each module/feature you will find links to files in the GitHub repository to copy.
.NET 8
I am using .NET 8 because I want to explore new version. Surely a lot of the code can be compatible with .NET 6 and earlier. If you can't migrate to a newer version than just make couple of twicks and code will work.
You own the code, so it's on you.
