nbdev_readme only generates README in `docs` folder and not in main folder

Hi, I am using the `nbdev_readme` command to generate the README file from `index.ipynb`. My repo looks as following (simplified):

.
├── nbs/
│ └── index.ipynb
├── _proc/
│ └── docs/
│ └── README.md
├── settings.ini
├── setup.py
└── README.md

The problem I encounter is that when running `nbdev_readme`, only the README.md from `_proc/docs/` is updated, and not the one in the main folder. This is what I get as terminal output:


I am doing something wrong or is this intended? What can I change to have the automatic README update from the main folder?

Thanks!
