+## Setup Open w/ VS Code
+
+unfortunately, multi-cursor support is pretty basic in Visual Studio. 
+Our suggestion is to jump to VS Code whenever you have a more 
+advanced multi-cursor use-case. 
+Here's how to set up Visual Studio to this easily.
+
+1. Go to Tools->External Tools...
+2. Click "Add" 
+3. Title: `&1 vscode`
+4. Command: `"your\path\to\vscode\code.exe"`
+5. Arguments: `. -g $(ItemPath):$(CurLine):$(CurCol)`
+6. Initial directory: `$(SolutionDir)`
+7. Click "OK"
+
+In the end, it should look something like this:

+
+After this, pressing the following key sequence (one at a time) `alt t 1` 
+will open the current document in VS code at the current cursor position.
