+
+### Development
+
+During development, the container uses `dotnet watch` to enable automatic reloads when files change. The development server is started with:
+
+```sh
+dotnet watch --no-launch-profile
+```
+
+This will:
+- Use `dotnet watch` to monitor for changes to .cs, .razor, and .css files and restart the server when changes are detected.
+- Run the Blazor Server application with hot reload enabled.
+- Start the app on port 5054.
+- Enable automatic browser refresh when Razor components or CSS files change.
+
+### Production
+ 
+Builds a production-ready image. During the build, dependencies are restored with `dotnet restore` and the application is published with `dotnet publish`. When the container starts, it runs:
+
+```sh
+dotnet component-blazor.dll
+```
+
+This uses the compiled .NET application optimized for production deployment.
+
+### Data Protection
+
+The application uses ASP.NET Core Data Protection for securing authentication cookies and anti-forgery tokens. In Kubernetes deployments, data protection keys are persisted using a PersistentVolumeClaim to ensure session continuity across pod restarts.
