+Hello from Docker!
+This message shows that your installation appears to be working correctly.
+
+To generate this message, Docker took the following steps:
+ 1. The Docker client contacted the Docker daemon.
+ 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
+    (windows-amd64, nanoserver-ltsc2022)
+ 3. The Docker daemon created a new container from that image which runs the
+    executable that produces the output you are currently reading.
+ 4. The Docker daemon streamed that output to the Docker client, which sent it
+    to your terminal.
+
+To try something more ambitious, you can run a Windows Server container with:
+ PS C:\> docker run -it mcr.microsoft.com/windows/servercore:ltsc2019 powershell
+
+Share images, automate workflows, and more with a free Docker ID:
