+<h2>GatorTron-Base overview </h2>
+
+Developed by a joint effort between the University of Florida and NVIDIA, GatorTron-Base is a large language model of 345 million parameters, pre-trained using a BERT architecure implemented in the Megatron package (https://github.com/NVIDIA/Megatron-LM). 
+
+GatorTron-Base is pre-trained using a dataset consisting of:
+
+- 82B words of de-identified clinical notes from the University of Florida Health System,
+- 6.1B words from PubMed CC0,
+- 2.5B words from WikiText,
+- 0.5B words of de-identified clinical notes from MIMIC-III
+
+<h2>De-identification</h2>
+
+We applied a de-identification system to remove protected health information (PHI) from clinical text. We adopted the safe-harbor method to identify 18 PHI categories defined in the Health Insurance Portability and Accountability Act (HIPAA) and replaced them with dummy strings (e.g., replace people’s names into [\*\*NAME\*\*]). 
+
+The de-identifiation system is described in:
