-# This is a demo

-Thanks for reading. Bye!
+
+A simple ASP.NET Core Web API CRUD app using PostgreSQL.
+
+## Local development
+
+Requirements:
+- .NET SDK
+- Docker
+
+### Run with docker-compose
+
+```powershell
+cd .\demo001
+docker-compose up --build
+```
+
+The API will be available at `http://localhost:5000`.
+
+### API endpoints
+
+- `GET /api/TodoItems`
+- `GET /api/TodoItems/{id}`
+- `POST /api/TodoItems`
+- `PUT /api/TodoItems/{id}`
+- `DELETE /api/TodoItems/{id}`
+
+### Notes
+
+- `Dockerfile` is ready for container builds.
+- `docker-compose.yml` starts PostgreSQL and the API locally.
+- Later you can reuse the Docker image for Kubernetes deployment.

+Use VS Code Remote SSH to build on the Linux server
+1. Install the Remote SSH extension
+Install Remote - SSH from the VS Code Extensions view.
+2. Add your SSH host
+Open Command Palette: Ctrl+Shift+P
+Run Remote-SSH: Add New SSH Host...
+Enter something like:
+ssh root@your.remote.server
+Choose the SSH config file to save it.
+3. Connect to the remote host
+Open Command Palette: Ctrl+Shift+P
+Run Remote-SSH: Connect to Host...
+Select root@your.remote.server
+VS Code will open a new window connected to the remote machine.
+4. Open your project folder on the remote server
+In the remote VS Code window, use File > Open Folder...
+Open the project directory on the Linux server
+If your project is only local, copy it to the remote host first, or clone it there from git.
+5. Build and run remotely
+Open a terminal in VS Code (`Ctrl+``)
+This terminal runs on the remote Linux machine
+Run:
+dotnet restore
+dotnet build
+dotnet run
+6. If you want Docker/Compose on the remote
+Since you have root access on the server, you can install Docker there and use it remotely:
+
+Install Docker on remote Linux
+Install Docker Compose plugin if needed
+Run:
+docker compose up --build
+7. Optional: Use remote ports
+If your API listens on 5000, you can forward that port from remote to local using VS Code Remote Explorer or the prompt when the app starts.
+Why this works
+VS Code Remote SSH lets you edit locally while using the remote machine for:
+building
+restoring packages
+running the app
+optionally building Docker images
+Quick summary
+Install Remote - SSH
+Add root@your.server
+Connect & open remote folder
+Build in remote terminal
+If you want, I can also give you the exact ~/.ssh/config entry and the commands to install Docker on the remote Linux server.
