README: What is </path/to/data>

Following the readme, I'm not sure what to do at this point.... Should I have already created `/https` and `/http`?
```
git clone https://github.com/reservoirgenomics/httpfs.git
pip install -r httpfs/requirements.txt
python /internal-services/httpfs/httpfs.py /https https --lru-capacity 1000 --disk-cache-dir /data/disk-cache --disk-cache-size 4294967296
python /internal-services/httpfs/httpfs.py /http http --lru-capacity 1000 --disk-cache-dir /data/disk-cache --disk-cache-size 4294967296
python /internal-services/httpfs/httpfs.py /http ftp --lru-capacity 1000 --disk-cache-dir /data/disk-cache --disk-cache-size 4294967296
```
