_DESCRIPTION = """\
RISCBAC was created using [RISC](https://github.com/GRAAL-Research/risc), an open-source Python package data 
generator. RISC generates look-alike automobile insurance contracts based on the Quebec regulatory insurance 
form in French and English.

It contains 10,000 English and French insurance contracts generated using the same seed. Thus, contracts share 
the same deterministic synthetic data (RISCBAC can be used as an aligned dataset). RISC can be used to generate 
more data for RISCBAC.
