+## ⚙️ Installation
+
+Before using the debugger, ensure the extension is installed using the `vsce` tool.
+
+```bash
+npx vsce package
+code --install-extension Hyperledger-Fabric-Debugger.vsix
+```
+
+## 🚀 Launching the Extension
+Open VSCode and navigate to the Run & Debug tab on the sidebar.
+
+Click the "Run Extension" button.
+![Start extension](./images/extension-start.png)
+
+This will open the Extension Development Host, where the debugger's custom UI will appear.

+
+## 🧩 Using the Extension Features
+Once the extension UI is open, you’ll see the main dashboard with the following actions:
+
+- **Upload Network Configuration** (e.g., connection profile)

+
+- **Start Local Network** (e.g., using fabric-samples)
+
+- **Query Blocks**

+
+## 🐛 Running the Debugger
+To start debugging your chaincode:
+
+1. Click **Run & Debug**.
+
+2. Select the configuration: **Debug Hyperledger Fabric**. 
+![Start Debugger](./images/debugger-start.png)
+
+3. A file prompt will appear — select your `chaincode.go` file.
+![File Prompt Window](./images/select-chaincode-file.png)
+
+4. The debugger will attach using **Delve**.
+
+5. Set breakpoints in your code.

+
+You’ll see the standard VSCode debug interface:
+
+Variables

+
+6. Use a Fabric client to invoke chaincode.
+
+## ✅ Example Flow
+- Upload network config & wallet.
+- Upload your `chaincode.go` file.
+- Add breakpoints.
+- Use a Fabric client to invoke transactions.
+- Observe how the debugger halts at breakpoints, shows local variables, and logs chaincode behavior in real time.
+
+## 🧼 Troubleshooting
+If you encounter errors like Delve DAP server not found:
+
+- Ensure `dlv` is installed on your machine:
+```bash
+ go install github.com/go-delve/delve/cmd/dlv@latest
+ 
+ ```
+
+Restart the extension host and re-select the debug config.
