 scalable Python package for BIDS App analysis of large datasets.
 It uses `DataLad <https://www.datalad.org/>`_ and adopts
 the `FAIRly big framework <https://doi.org/10.1038/s41597-022-01163-2>`_.
-Currently it is compatible with SGE and Slurm clusters.
+Currently, BABS supports jobs submissions and audits on Sun Grid Engine (SGE) and Slurm
+high performance computing (HPC) clusters with a parsimonious set of programs.

+Background and Significance
+-------------------------------
+
+Neuroimaging research faces a crisis of reproducibility.
+With massive sample sizes and greater data complexity, this problem becomes more acute.
+The BIDS Apps - the software operating on BIDS data - have provided a substantial advance.
+However, even using BIDS Apps, a full audit trail of data processing is a necessary prerequisite for fully reproducible research.
+Obtaining a faithful record of the audit trail is challenging - especially for large datasets.
+Recently, the `FAIRly big framework <https://doi.org/10.1038/s41597-022-01163-2>`_
+was introduced as a way to facilitate reproducible processing of large-scale data
+by leveraging `DataLad <https://www.datalad.org/>`_ - a version control system for data management.
+However, the current implementation of this framework remains challenging to general users. 
+
+BABS was developed to address these challenges
+and to facilitate the reproducible application of BIDS Apps to large-scale datasets.
