+# EntityInjector.Samples.CosmosTest
+
+This sample demonstrates how to use EntityInjector with a Cosmos database using the docker linux emulator.  
+It shows how to bind route parameters directly to entities using dependency injection.
+
+Note that due to issues with the cosmos emulator we have added a retry on each test.
+
+## Prerequisites
+
+- Docker installed and running
+- .NET 8 SDK installed
+
+## How to run
+
+1. From the repository root, start the database using Docker Compose:
+
+```bash
+docker compose up --build
+```
+
+This will create a Cosmos container which can be easily browsed on localhost:1234.
+
+2. From the sample project directory, build and run the tests:
+
+```bash
+dotnet clean && dotnet restore && dotnet test
+```
