QuickStart to get started.
Properties descibes FsCheck's language to express tests - in other frameworks these are often called parametrized tests or generative tests. FsCheck calls them properties.
Generating test data describes how to guide FsCheck to generate better data or to stop it from generating data that doesn't make sense for what you're trying to test. FsCheck has a flexible language to describe test value generators and shrinkers, and apply them to your properties.
Model based testing is a particular testing approach where FsCheck generates a large number of random operations on an object or data structure, and the results of each operation are compared with a (much simpler) model.
Running Tests explains various ways to run FsCheck tests and how to integrate with unit testing frameworks.
API Reference contains automatically generated documentation for all types, modules and functions.
Model based testing vNext (Experimental) is a relatively new addition for a more powerful model based testing. It's still a bit rough around the edges, some things may not work, and it is subject to change (i.e. no promises regarding semantic versioning and breaking changes). Regardless, feedback is very much appreciated!
