Documentation VS Misc-ML-Scripts

There is the current docs, and the v11 docs

I assumed you were building your project using the Avalonia template which would set you up for creating an MVVM project. If you were following the tutorial in your original post then it should be set up as MVVM. Try running some of the tutorials in the Avalonia Documentation to get a better feel for building in Avalonia.

There were no docs on the MaskedTextBox, only some of WPF so I decided to be a good boy scout and write them myself with my second PR on AvaloniaDoc.

Docs content are huge help for maintainers, mostly because they are developers, they are not interested in writing docs, but fixing bugs. Even Avalonia which is great project on itself, suffer from lack of docs. For example https://github.com/AvaloniaUI/Documentation/issues/304 where they have functionality which is supported, but it is not documented anywhere. If you novice, Avalonia hard to get started, if you know WPF already, that's relatively easy.

Start with something extremely small. That's approximately the same as just politely greet unknown person. For example https://github.com/mariari/Misc-ML-Scripts/pull/1 where I just looking at repo for some other information and notice that some symbols was displayed incorrectly. So I just fix a typo. Admittely while I write this PR was already accepted.
