-## Feature selection in Spark
+### Memory-Efficient, High-Performance Feature Selection Library for Big and Small Datasets
 
 ### Description
 
-`fsspark` is a python module to perform feature selection and machine learning based on spark.

+`fslite` is a python module to perform feature selection and machine learning using pre-built FS pipelines. 
+Pipelines written using `fslite` can be divided roughly in four major stages: 1) data pre-processing, 2) univariate 
 filters, 3) multivariate filters and 4) machine learning wrapped with cross-validation (**Figure 1**).
 
+`fslite` is based on our previous work [feseR](https://github.com/enriquea/feseR); previously implemented in R and caret package; publication can be found [here](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0189875).
