+# WireMock.Net.Testcontainers 
+WireMock.Net.Testcontainers uses [Testcontainers for .NET](https://dotnet.testcontainers.org/) to spinup a docker container directly from the C# (unittest) code. 
+
+This options requires docker service running locally.
+
+Both the [Linux](https://hub.docker.com/repository/docker/sheyenrath/wiremock.net) and the [Windows](https://hub.docker.com/repository/docker/sheyenrath/wiremock.net-windows/general) version from WireMock.Net are supported.
+
+## Usage
+### Build and Start
+To build a container and startup this container, use this code:
+``` C#
+var container = new WireMockContainerBuilder()
+    .WithAutoRemove(true)
+    .WithCleanUp(true)
+    .Build();
+
+await container.StartAsync().ConfigureAwait(false);
+```
+
+#### Methods
+The following builder methods are available for the `WireMockContainerBuilder`:
+
+| Method |  Example | What |
+| -      | -        | -    |
+| `WithMappings` | `.WithMappings(@"C:\example\\mappings")` | Specifies the path for the (static) mapping json files.
+| `WithWatchStaticMappings` | `.WithWatchStaticMappings(true)` | Watch the static mapping files + folder for changes when running.
+| `WithAdminUserNameAndPassword` | `.WithAdminUserNameAndPassword("x", "y")` | Set the admin username. and password for the container (basic authentication).
+
+## Usage in Unit Test
+Follow the tutorial [here](https://github.com/testcontainers/testcontainers-dotnet/blob/develop/examples/WeatherForecast/tests/WeatherForecast.Tests/WeatherForecastTest.cs) and make sure to use WireMock.Net container instead of the container used in that example.
