As an example, this notebook should be cleaner and self-contained for illustration purposes.

1. git clone is better compared with extracting a local zip file, since how you download the "/content/drive/My Drive/DrQA-master.zip" is not in this notebook. You can directly clone into the target directory in this step.
2. Non-related lines should be removed. For example, "Create a file in Drive." and "New Section" do not seem to be related to this project.
