+[Visual Studio Code](https://code.visualstudio.com/) is a powerful text editor which can be expanded to a full featured integrated development environment (IDE) with plugins. To debug a program make sure to install the [C/C++ Extension Pack](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools-extension-pack) which includes support for CMake and debugging with `gdb`.
+
+Then in the editor:
+
+1. Open e.g. `ogs.cpp`.
+2. Set a [breakpoint](https://code.visualstudio.com/docs/editor/debugging#_breakpoints) in the first line of the `main()`-function (around line 58) by clicking on the left gutter in the editor window (a red dot marks the enabled breakpoint).
+3. Click on the `CMake`-sidebar.
+4. Make sure that `debug` is the active configure and build preset.
+5. Click the `Build`-button in the status bar.
+6. Click the bug icon in the status bar.

+
+After some seconds the debugger starts and halts at the specified breakpoint indicated y the yellow marker around the breakpoint and line. You can now step into or over statements with debugger controls at the top of the window:

+
+To debug with specific arguments to `ogs`, e.g. for setting a `.prj`-file:
+
+1. Click on the `Debug`-sidebar.
+2. Click on `create a launch.json file`.
+3. Click `Add Configuration`.
+4. Select `C/C++: (gdb) Launch`
+
+![Setup a launch.json file](vscode-debugging-3.png)
+
+Edit the file e.g. like this:
+
+```json
+"program": "${workspaceFolder}/../build/debug/bin/ogs",
+"args": ["${workspaceFolder}/Tests/Data/Parabolic/ComponentTransport/ReactiveTransport/CO2Injection/cl.prj"],
+"cwd": "${workspaceFolder}/../build/debug/_out",
+```
+
+This sets the program to debug to the `ogs`-binary in the debug build folder, sets a specific `.prj`-file to run and sets the working directory (output folder) to some `_out`-subfolder in the build directory.
+
+You can also give the debug configuration some meaningful name, e.g. `"name": "Debug cl.prj",` which results in a new button in the status bar:

+Click on it to start the debug session.
