+## Debugging
+
+The extension uses the debugger from Microsoft's
+[C/C++ extension](https://github.com/Microsoft/vscode-cpptools)
+for Visual Studio Code. This allows this extension to use the full functionality
+of the C/C++ extension for debugging applications:
+(un)conditional breaking points, expression evaluation, multi-threaded debugging,
+call stack, stepping, watch window.
+
+A minimal `launch.json` script, responsible for controlling the debugger, is
+provided below. However, Visual Studio Code is also capable of autogenerating
+a `launch.json` file and the configurations inside the file.
+
+More details about how to setup the debugger can be found in Microsoft's website:

 ## Requirements
 
 For the linter to work you need to have `gfortran` on your path, or wherever you configure it to be.
 
+For debugging you need to have one of the following debuggers installed:
+
+- **Linux**: GDB
+- **macOS**: GDB or LLDB
+- **Windows**: GDB  or Visual Studio Windows Debugger
+
