+# Remote Debugging tuliprox in VSCode with Docker
+
+This guide explains how to set up remote debugging for the tuliprox project in VSCode using a Docker container.
+
+## Prerequisites
+
+- VSCode with the following extensions:
+  - [CodeLLDB](https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb)
+  - [Docker](https://marketplace.visualstudio.com/items?itemName=ms-azuretools.vscode-docker)
+- Docker and Docker Compose installed
+- Rust toolchain (if building locally)
+
+## Setup
+
+1. Copy the debug configuration files to your project root:
+   ```bash
+   cp -r docker/debug/.vscode .
+   cp docker/debug/docker-compose.debug-override.yml .
+   ```
+
+## Configuration
+
+### Docker Compose
+The `docker-compose.debug-override.yml` file:
+- Configures LLDB debug ports (10586 for control, 10600-10700 for sessions)
+- Sets up privileged mode for debugging
+- Mounts cargo cache volumes for faster builds
+- Uses the debug build target
+
+### VSCode Tasks
+The `.vscode/tasks.json` defines:
+- `docker-compose-up-debug`: Builds and starts containers with debug config
+- `docker-compose-down`: Stops and removes containers
+
+### VSCode Launch Configurations
+The `.vscode/launch.json` provides two debug configurations:
+1. **Docker Remote Debug (start & attach)**:
+   - Automatically starts containers and attaches debugger
+   - Uses the `docker-compose-up-debug` pre-launch task
+2. **Docker Remote Debug (attach only)**:
+   - Only attaches debugger to running container
+
+## Debugging Workflow
+
+1. Open the project in VSCode
+2. Set breakpoints in your Rust code
+3. Select the debug configuration from the Run and Debug panel:
+   - Use "Docker Remote Debug (start & attach)" for a complete start-to-debug workflow
+   - Use "Docker Remote Debug (attach only)" if containers are already running
+4. Press F5 to start debugging
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Debugger fails to connect**:
+   - Verify ports 10586 and 10600-10700 are available
+   - Check Docker container logs for errors
+   - Ensure the container is running in privileged mode
+
+2. **Breakpoints not hitting**:
+   - Verify source mapping is correct in launch.json
+   - Ensure you're using the debug build (`target/debug/tuliprox`)
+
+3. **Performance issues**:
+   - The debug build is slower than release
+   - Consider adding more RAM to Docker if needed
+
+### Debugging Tips
+
+- Use the VSCode debug console for LLDB commands
+- The debugger supports all standard LLDB features (watch, call stack, etc.)
+- Breakpoints can be set while the program is running
