[git] What's the best practice to "git clone" into an existing folder?

Usually I will clone the initial repository first, and then move everything in the existing folder to the initial repository. It works every time.

The advantage of this method is that you won't missing anything of the initial repository including README or .gitignore.

You can also use the command below to finish the steps:

$ git clone https://github.com/your_repo.git && mv existing_folder/* your_repo
