First of all fork the project you want to study on.
Create your folder on your OS.
Important !: Open Terminal by right-clicking in the new created folder. So you don't need to write anything to find your folder you are here..
Copy url that you want to clone.
And write down only git clone to your terminal window and paste the url. and push Enter
In the example:
git clone https://github.com/MesutBE/functions-to-methods.git
To begin VSCode you don't need to try to find your project. Open Terminal by right-clicking in your project's folder. And type code .. That's all!
