 ### 🟢 RegionSet
 
 RegionSet is Python representation of a genomic region set, commonly named as BED file.

 # gtars-tokenizers
 
-Genomic region tokenizers for machine learning applications.
+The gtars package contains genomic tokenizers module. 
+These are used to convert genomic interval data from disparate sources into a consistent universe or consensus set. 
+Primarily, the tokenizers are used to standardize input into our machine learning models.
+
+<p align="center">
+  <img align="center" src="../img/tokenization.svg" width="600" />
+</p>
+
+A minimal tokenizer requires a bedfile. 
+Once instantiated, this tokenizer can be used to tokenize new genomic interval data into the model's vocabulary.
