 ## Docker Deployment
 
+NLWebNet supports two container build approaches:
+1. **Traditional Dockerfile** (recommended for CI/CD and complex scenarios)
+2. **.NET SDK Container Build** (modern, simplified approach for development)

+### .NET SDK Container Build (Modern Approach)
+
+.NET 9 SDK includes built-in container support that eliminates the need for a traditional Dockerfile:
+
+```bash
+# Navigate to the demo project
+cd samples/Demo
+
+# Build and publish as container
+dotnet publish -c Release -p:PublishProfile=DefaultContainer
+
+# The container image will be available as 'nlwebnet-demo:latest'
+# Run the container
+docker run -p 8080:8080 nlwebnet-demo:latest
+```
+
+**Benefits of .NET SDK Container Build:**
+- No Dockerfile required
+- Optimized .NET base images
+- Automatic security updates
+- Simplified build process
+- Better layer caching
+
+**Configuration:**
+Container settings can be customized in the project file:
+```xml
+<PropertyGroup>
+  <ContainerImageName>nlwebnet-demo</ContainerImageName>
+  <ContainerImageTag>latest</ContainerImageTag>
+  <ContainerPort>8080</ContainerPort>
+</PropertyGroup>
+```
