+The examples were written as cross platform console application using c++11. It means that you should be able to compile and execute those examples with any recent compiler.
+
+we recommend working with Visual Studio Code because it is a lightweight and cross-platform tool .It is a very complete IDE and is available for free (https://code.visualstudio.com/). You may need to install c++ extension and the compiler you prefer (The extension is still in preview and its focus is code editing, navigation, and debugging support for C and C++). For more information on how to use VSCode with c++ refer to: https://code.visualstudio.com/docs/languages/cpp .
+
+For code execution in VSCode you will need to set up your task first. An example using g++ :  
+
+```sh
+{
+    "version": "2.0.0",
+    "tasks": [
+        {
+            "label": "build",
+            "type": "shell",
+            "command": "g++ -g -std=c++11 Conceptual/main.cc -o main",
+            "group":{
+                "kind": "build",
+                "isDefault": true    
+            },
+            "problemMatcher":"$gcc"
+        }
+    ]
+}
+```
+Then you just need to start the executable.In case you have some doubts here you have an useful [tutorial] using vscode.   
 
 ## Contributor's Guide
 
-TODO
+I appreciate any help, whether it's a simple fix of a typo or a whole new example. Just make a fork, make your change and submit a pull request.
+
+Here's a style guide which might help you to keep your changes consistent with the rest of the project's code:
+
+1. All code should match the [Google style guide].
+2. Aim to put all code within one .cc file. Yes, I realize that it's not how it supposed to be done in production. However, it helps people to understand examples better, since all code fits into one screen.
+3. The comments doesn't follow the style guide for compatibility reasons withe other language examples.
