There is a Wiki, which explains things such as (intended) nonstandard behavior. Also, watching the GitHub repository is a good way to learn both what is and isn't implemented in VsVim and also to learn Vim features that you didn't know about. I've certainly learned a number of things about Vim from feature requests that are posted there, etc.
There are many things missing from the VsVim implementation, and there always will be. There are just certain areas of Visual Studio that you can't accurately layer Vim on top of (for example, the mismatch between the way Visual Studio handles documents, windows and tabs and the way that Vim handles buffers, windows and tabs). However, more and more is supported continuously, and you can always submit a pull request. Jared is very friendly and good to work with. I started using VsVim a year and a half ago and already much more is supported then when I started using it.
If you are wondering whether you are doing somethign wrong or whether it just isn't implemented in VsVim, a good thing to do is to pop open Vim and use its :help
feature to find out. You can always submit an issue on GitHub, or if you really want to learn Vim in a detailed way, you could work on implementing a feature.
Finally, the documentation is incomplete, but since it is a wiki, you are welcome to contribute to it as you learn.
