# Overview


For a guided introduction to essential NServiceBus concepts start with the [NServiceBus step-by-step tutorial](/tutorials/nservicebus-step-by-step/index.md).

The samples are designed to highlight how various features of NServiceBus work and how the extension points plug into other libraries and tooling. See [about the samples](/samples/about.md) for important information about the samples and the code contained within them.

The samples are located in GitHub at [Particular/docs.particular.net/samples](https://github.com/Particular/docs.particular.net/tree/master/samples) and both [issues](https://github.com/Particular/docs.particular.net/issues) and [pull requests](https://help.github.com/articles/using-pull-requests/) are accepted.
