 FastCloner uses caching by default, which makes evaluating properties harder. Cloning unmanaged resources, such as `IntPtr`s may result in side-effects, as there is no metadata for the length of buffers such pointers often point to. `ReadOnly` and `Immutable` collections are tested to behave well if they follow basic conventions. Many other features, such as cloning `Dictionary`ies properly while keeping hashcodes, `INotifyPropertyChanged`, `delegate`s, `event`s, `HttpRequest`s / responses, and others are supported. If something doesn't work out of the box, let me know in the [issues](https://github.com/lofcz/FastCloner/issues), the repository is actively maintained.

 ## Performance
 
-FastCloner aims to _work correctly_ and meet reasonable expectations by default while being fast. Benchmarking results are available [here](https://github.com/lofcz/FastCloner/tree/next/FastCloner.Benchmark), check them out! By default, fast cloner relies on heavily cached reflection to work. An incremental source generator is currently in development as an opt-in alternative for performance-critical scenarios.

+## Contributing
+
+If you are looking to add new functionality, please open an issue first to verify your intent is aligned with the scope of the project. The library is covered by [~300 tests](https://github.com/lofcz/FastCloner/tree/next/FastCloner.Tests), please run them against your work before proposing changes. When reporting issues, providing a minimal reproduction we can plug in as a new test greatly reduces turnaround time.
