+## V language support
+
+The [V VS Code Extention](https://marketplace.visualstudio.com/items?itemName=vlanguage.vscode-vlang)
+provides V language support for Visual Studio Code.
+
+![Screenshot Code with activated extention](https://github.com/vlang/vscode-vlang/raw/HEAD/images/demo.png)
+
+**Features:**
+* Syntax Highlighting.
+* Code Snippets for quick coding.
+* Format code on file save as well as format manually (using v fmt).
+* Linter (Workspace files only).
+[more](https://marketplace.visualstudio.com/items?itemName=vlanguage.vscode-vlang)
+
+**Hint:** This extention will not add the V compiler! Information on how to
+[install V compiler](https://github.com/vlang/v/blob/master/doc/docs.md#install-from-source)
+on your operating system.
+
+### Setup Extention
+
+Install [V VS Code Extention](https://marketplace.visualstudio.com/items?itemName=vlanguage.vscode-vlang).
+
+## Visual Debugging
+
+![screenshot visual debugger](https://github.com/vlang/v/blob/master/doc/img/vscode-debugger.png?raw=true)
+
+The [C/C++ Extention](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools)
+for Visual Studio Code provides visual conditional debugging.
+
+**Features:**
+* Conditional breakpoints
+* Function breakpoints
+* Expression evaluation
+* Change Values
+[more Features & Documentation](https://code.visualstudio.com/docs/cpp/cpp-debug)
+
+**Hint:** Not all types (e.g. Array) in V currently create the required
+[DWARF](https://en.wikipedia.org/wiki/DWARF) information to show and
+edit the variable.
+
+### Setup Debugging
+
+1. Install the [C/C++ Extention](https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools)
+2. Open `RUN AND DEBUG` panel (Debug Icon in left panel).
+3. Click on `Show` all automatic debug configurations.
+4. Select `Add config`.
+5. Select environment `C++ (GDB/LLDB)`.
+6. Change the line `"program": "Enter the program name, e.g. \"${workspaceFolder}/a.out\"",`
+to point to your compiled application e.g. `"program": "${workspaceFolder}/hello",`.
+
+This will add a block to your `.workspace` file,
+or create the file `.vscode/launch.json`:
+```json
+{
+ // Use IntelliSense to learn about possible attributes.
+ // Hover to view descriptions of existing attributes.
+ // For more information, visit:
+ // https://go.microsoft.com/fwlink/?linkid=830387
+ "version": "0.2.0",
+ "configurations": [
+ {
+ "name": "(lldb) Start",
+ "type": "cppdbg",
+ "request": "launch",
+ "program": "Enter the program name, e.g. \"${workspaceFolder}/a.out\"",
+ "args": [],
+ "stopAtEntry": false,
+ "cwd": "${fileDirname}",
+ "environment": [],
+ "externalConsole": false,
+ "MIMode": "lldb"
+ }
+ ]
+}
+```
+
+**Optional:** use `"program": "${fileDirname}/${fileBasenameNoExtension}"` to debug
+any current open source file with an existing binary with the same name but without any extension.
+
+### Usage
+
+To allow your compiled application to be debugged.
+The application needs to include additional debugging information
+([DWARF](https://en.wikipedia.org/wiki/DWARF)).
+
+**1. Compile with debugging information:**
+`v -b c -g hello.v -o hello` or short `v -g hello.v`
+
+The `-g` option will add the needed debugging informations.
+More Options are explained in the [docs](docs.md#debugging).
+
+
+**2. Start Debugging**
+
+1. Open your source code and set the required break points
+2. Click on the Debug Icon in the left Icon panel and click
+`> (lldb) Start`, or use `F5` to launch your application in debug mode.
+
+For all options look at the official
+[C/C++ Extention documentation](https://code.visualstudio.com/docs/cpp/cpp-debug).
