-To debug a pocketpy program, you need to install our VSCode extension first:
+You can install our VSCode extension to debug pocketpy scripts.

-
-!!!
-The VSCode extension requires pocketpy version >= `2.1.1`
-!!!
-
-## Create a `launch.json` file
-
-Navigate to the Debug view in VSCode, and click on "create a launch.json file" link.
-In the dropdown menu, select "pocketpy".
-
-![launch_json](../static/debugger/launch_json.png)
-
-Then a default `launch.json` file will be created in the `.vscode` folder
-with a sample pocketpy debug configuration.
-
-## How does it work?
-
-pocketpy provides a C-API `py_debugger_waitforattach`,
-which starts a debug server and waits for the VSCode extension to attach.
-When the debugger is attached, the program will continue to run.
-
-+ If you are using pocketpy's standalone executable `main.exe`, you can pass `--debug` flag to it. This will automatically call `py_debugger_waitforattach("localhost", 6110)` before running your program.
-+ If you are embedding pocketpy as a library, you need to call `py_debugger_waitforattach` manually in your C/C++ code.
-
-## Configuration
-
-+ `type`: must be `pocketpy`
-+ `request`: can be `attach` or `launch`
-+ `name`: the name of this configuration
-+ `port`: the port number of the debug server, must match the one in `py_debugger_waitforattach`
-+ `host`: the host of the debug server, must match the one in `py_debugger_waitforattach`
-+ `sourceFolder`: the root folder of your python source code, default to `${workspaceFolder}`. However,
-sometimes you may run your program from a subfolder, in this case you need to set `sourceFolder` to the correct path. If this is not set correctly, breakpoints will not be hit.
-+ `program`: (for launch mode only) the path to the executable file which calls `py_debugger_waitforattach`, e.g. the pocketpy standalone executable `main.exe`.
-+ `args`: (for launch mode only) the arguments to pass to the executable file, e.g. `--debug` and the script path if you are using `main.exe`.
-+ `cwd`: (for launch mode only) the working directory to launch the executable file, default to `${workspaceFolder}`.
-
-### For attach mode
-
-In this mode, you need to start your pocketpy program manually which must call `py_debugger_waitforattach` first.
-After the program starts, you can let VSCode attach to the debug server.
-
-```json
-{
-    "type": "pocketpy",
-    "request": "attach",
-    "name": "Attach to pocketpy program",
-    "port": 6110,
-    "host": "localhost",
-    "sourceFolder": "${workspaceFolder}"
-}
-```
-
-### For launch mode
-
-In this mode, VSCode will start your program with the specified `program`, `args` and `cwd`.
-After the program starts, VSCode attempts to attach to the debug server automatically.
-
-```json
-{
-    "type": "pocketpy",
-    "request": "launch",
-    "name": "Launch pocketpy program",
-    "port": 6110,
-    "host": "localhost",
-    "sourceFolder": "${workspaceFolder}",
-    "program": "${workspaceFolder}/pocketpy/main.exe",
-    "args": [
-        "--debug"
-    ],
-    "cwd": "${workspaceFolder}"
-}

 With pocketpy VSCode extension, press `F1` and type `pocketpy: Load Line Profiler Report`,
 select **1. the `profile_report.json` file; 2. the source root of the program**. Then you will see a nice visualization of the profiling result.
