+# Child Process Debugging
+
+Cxbx is currently engineering to create and run a new instance of itself (`Cxbx.exe`), known as a child process.
+
+For development, it is strongly recommended you install [Microsoft Child Process Debugging Power Tool](https://marketplace.visualstudio.com/items?itemName=GreggMiskelly.MicrosoftChildProcessDebuggingPowerTool) to support child process debugging from within Visual Studio.
+
+Once setup, the extension attaches automatically, and supports all the standard IDE features - **although will not detect symbols inside XBE memory regions** - mapping instead to the `virtual_memory_placeholder` placeholder stub (you will still see callstacks though).
+
+## Setup
+
+Install the extensions. You will need to close down any open Visual Studio instances first.
+
+1. Open the Cxbx-Reloaded project file
+2. Open the new configuration window from `Debug -> Other Debug Targets -> Child Process Debugging Settings`
+3. From here, check `Enable child process debugging`
+4. In the table, double-click to add a new row, and enter `Cxbx.exe` as the process name
+5. Leave Action as `Attach Debugger` and `Debugger Type` as `<Inherit from parent process>`
+6. Make sure `Persist settings to` is set to `Hidden solution user options file (SUO file)` and hit Save (top right)
+
+You just need to do this once.
+
+## Usage
+
+Once emulation has started, Visual Studio will list 2 `Cxbx.exe` processes on the toolbar
+
+You can re-show this toolbar by checking `View -> Toolbars -> Debug Location`)
+
+The emulated process will have 2 threads named **Cxbx NV2A VBLANK** and **Cxbx NV2A FIFO**
+
+
+## Cxbx Debugger Workflow
+
+The Cxbx-Reloaded project includes a basic debugger (written in C#) to support extra Xbox-specific emulation features in addition to debugging the child process.
+
+**Only one user-mode debugger can be attached to a process at one time**
+
+With the Child Process extension, you will need to:
+
+1. Open the Cxbx-Reloaded project file
+2. Open the new configuration window from `Debug -> Other Debug Targets -> Child Process Debugging Settings`
+3. From here, disable Child Process Debugging on `Cxbx.exe`
+4. In the table, double-click to add a new row, and enter `CxbxDebugger.exe` as the process name
+5. Leave Action as `Attach Debugger`
+6. Set `Debugger Type` as `Managed (v4.6, v4.5, v4.0)`
+7. Make sure `Persist settings to` is set to `Hidden solution user options file (SUO file)` and hit Save (top right)
+
+You just need to do this once.
