I created a chrome extension to push all the updates on kaggle kernels and scripts to your Github repositories.

Once you have downloaded the extension, head back to your kaggle kernel / script and you will see a new Github button, click on the button and follow the instructions to push your updates to your Github repository. More info: https://www.kaggle.com/general/33479#post185147
