+## WireMock.Net
+Lightweight Http Mocking Server for .NET, inspired by [WireMock(http://WireMock.org) from the Java landscape.
+
+### :star: Key Features
+* HTTP response stubbing, matchable on URL/Path, headers, cookies and body content patterns
+* Library can be used in unit tests and integration tests
+* Runs as a standalone process, as windows service, as Azure/IIS or as docker
+* Configurable via a fluent C# .NET API, JSON files and JSON over HTTP
+* Record/playback of stubs (proxying)
+* Per-request conditional proxying
+* Stateful behaviour simulation
+* Response templating / transformation using Handlebars and extensions
+* Can be used locally or in CI/CD scenarios
+
+### :star: Stubbing
+A core feature of WireMock.Net is the ability to return predefined HTTP responses for requests matching criteria.
+See [Wiki : Stubbing](https://github.com/WireMock-Net/WireMock.Net/wiki/Stubbing).
+

+It's simple to install WireMock.Net as (global) dotnet tool, see [Wiki : dotnet tool](https://github.com/StefH/WireMock.Net/wiki/WireMock-as-dotnet-tool).
+
+#### As standalone process / console application
+This is quite straight forward to launch a mock server within a console application, see [Wiki : Standalone Process](https://github.com/StefH/WireMock.Net/wiki/WireMock-as-a-standalone-process).
+
+#### As a Windows Service
+You can also run WireMock.Net as a Windows Service, follow this [WireMock-as-a-Windows-Service](https://github.com/WireMock-Net/WireMock.Net/wiki/WireMock-as-a-Windows-Service).
+
+#### As a Web Job in Azure or application in IIS
+See this link [WireMock-as-a-(Azure)-Web-App](https://github.com/WireMock-Net/WireMock.Net/wiki/WireMock-as-a-(Azure)-Web-App)
+
+#### In a docker container
+There is also a Linux and Windows-Nano container available at [hub.docker.com](https://hub.docker.com/r/sheyenrath).
+For more details see also [Docker](https://github.com/WireMock-Net/WireMock.Net-docker).
