Step-1: Clone the original repo to your local machine

git clone https://github.com/handong1587/caffe.git caffe-yolo

cd caffe-yolo

Step-2: Create a new empty repo in your GitHub account

Step-3: Manually create the necessary remote links

git remote -v

Step-4: Rename origin to upstream and add our new empty repo as the origin

git remote rename origin upstream
git remote add origin https://github.com/handong1587/caffe-yolo.git
git remote -v

Step-5: Push from your local repo to your new remote one

git push -u origin master

Done.
