+Using Visual Studio Code (VS Code)
+====
+
+If you are working on Linux and OS X, you cannot use ISE because it is not supported on these platforms. 
+In this case, you can choose your favorite editor to write PowerShell scripts. 
+Here we choose VS Code as a PowerShell editor as an example.
+
+You can use VS Code on Windows with PowerShell V5 by using Windows 10 or by installing [Windows Management Framework 5.0 RTM](https://www.microsoft.com/en-us/download/details.aspx?id=50395) for down-level Windows OSs (e.g. Windows 8.1, etc.).
+
+Before starting it, please make sure PowerShell exists on your system. 
+By following the [Installing PowerShell](./learning-powershell.md#installing-powershell) instructions you can install PowerShell and launch a PowerShell session.
+
+Editing with VS Code
+----
+[**1. Installing VS Code**](https://code.visualstudio.com/Docs/setup/setup-overview)
+
+* **Linux**: follow the Installation instructions in the [Running VS Code on Linux](https://code.visualstudio.com/docs/setup/linux) to setup VS Code application
+
+
+* **OS X**: follow the Installation instructions in the [Running VS Code on OS X](https://code.visualstudio.com/docs/setup/osx) to setup VS Code application
+
+* **Windows**: download and install VS Code for your OS from [Visual Studio Code website](https://code.visualstudio.com/docs/setup/windows).
+
+
+**2. Installing PowerShell Extension**
+
+-	Launch the Visual Studio Code app by:    
+  *	**Windows**:      typing **code** in your PowerShell session
+  *	**Linux**:        typing **code .** in your terminal
+  *	**OS X**:         typing **code** in your terminal
+
+
+-	Press **F1** (or **Ctrl+Shift+P**) which opens up the “Command Palette” inside the VS Code app.
+-	In the command palette, type **ext install** and hit **Enter**. It will show all VS Code extensions available on your system.
+-	Choose PowerShell and click on **Install**, you will see something like below
+
+![VSCode](vscode.png)
+
+-	After the install, you will see the **Install** button turns to **Enable**.
+-	Click on **Enable** and **OK**
+-	Now you are ready for editing. 
+For example, to create a new file, click **File->New**. 
+To save it, click **File->Save** and then provide a file name, let's say "helloworld.ps1". 
+To close the file, click on "x" next to the file name. 
+To exit VS Code, **File->Exit**.
+
+
+Debugging with VS Code
+----
+
+-	Open a file folder (**File->Open Folder**) that contains the PowerShell modules or scripts you have written already and want to debug. 
+In this example, we saved the helloworld.ps1 under a directory called "demo". 
+Thus we select the "demo" folder and open it in VS Code.
+
+-	Creating the Debug Configuration (launch.json)
+
+  Because some information regarding your scripts is needed for debugger to start executing your script, we need to set up the debug config first. 
+  This is one-time process to debug PowerShell scripts under your current folder. 
+  In our case, the "demo" folder.
+
+  * Click on the **Debug** icon (or **Ctrl+Shift+D**)
+  * Click on the **Settings** icon that looks like a gear. 
+  VS Code will prompt you to **Select Environment**. 
+Choose **PowerShell**. 
+Then VS code will auto create a debug configuration settings file in the same folder. 
+It looks like the following:
+```json
+{
+    "version": "0.2.0",
+    "configurations": [
+        {
+            "name": "PowerShell",
+            "type": "PowerShell",
+            "request": "launch",
+            "program": "${file}",
+            "args": [],
+            "cwd": "${file}"
+        },
+        {
+            "name": "PowerShell x86",
+            "type": "PowerShell x86",
+            "request": "launch",
+            "program": "${file}",
+            "args": [],
+            "cwd": "${file}"
+        }
+    ]
+}
+```
+-	Once the debug configuration is established, go to your helloworld.ps1 and set a breakpoint by pressing **F9** on a line you wish to debug.
+-	To disable the breakpoint, press **F9** again.
+-	Press **F5** to run the script. 
+The execution should stop on the line you put the breakpoint on.
+- Press **F5** to continue running the script.
