+## Step 3: Install .NET 9 Runtime
+
+> **You must install the .NET 9 Runtime to run this app.**
+
+### 1. Go to the official .NET download page:
+
+- [https://dotnet.microsoft.com/download/dotnet/9.0](https://dotnet.microsoft.com/download/dotnet/9.0)
+
+### 2. Download the correct runtime:
+
+- Choose **".NET Runtime"** (not SDK).
+    - For Windows, select "x64" or "Arm64" depending on your machine.
+    - For Mac/Linux, pick the right option for your OS.
+
+### 3. Install:
+
+- Run the installer and follow the instructions.
+
+---
+
+## Step 4: Verify .NET Installation
+
+Open your **Command Prompt** (Windows) or **Terminal** (Mac/Linux) and run:
+
+```sh
+dotnet --version
+```
+
+- If it prints something like `9.0.x`, you are ready!
+
+---
+
+## Step 6: Run the API
+
+1. **Navigate** to the extracted folder.  
+   - Example (Windows):
+     ```sh
+     cd C:\HomeApi\dotnet
+     ```
+   - Example (Mac/Linux):
+     ```sh
+     cd ~/Downloads/HomeApi/dotnet
+     ```
+
+2. **Run the API**:
+   ```sh
+   dotnet HomeApi.dll
+   ```
+
+3. You should see output like:
+   ```
+   Now listening on: http://localhost:5000
+   Application started. Press Ctrl+C to shut down.
+   ```
+
+---
+
+## Step 6: Test the API
+
+- Open your web browser and go to:  
+  [http://localhost:5000/scalar](http://localhost:5000/scalar)
+- You should see an API documentation page.
+
+---
+
+## Stopping the API
+
+- Press `Ctrl+C` in the terminal window where the app is running.

+
+## FAQ
+
+**Q: I get 'dotnet is not recognized'?**  
+The .NET runtime is not installed or not added to your PATH. Re-install it and reboot your computer.
+
+**Q: How do I change the port?**  
+Open `appsettings.json` and look for URLs or configuration relating to ports. Edit as needed, or run with:
+```sh
+dotnet HomeApi.dll --urls "http://localhost:8080"
+```
+
+**Q: Do I need Visual Studio?**  
+No! You only need the .NET 9 Runtime.
+
+**Q: How do I call the API?**  
+You can use a browser for GET endpoints or tools like [Postman](https://www.postman.com/) or `curl` for others.
