-## Welcome to the Github Org for UCSD Bioinformatics!
+## Welcome to the Github Org for Bioinformatics at UC San Diego!
 
-This organization serves as a hub for documentation, code, and other materials to support bioinformatics at UCSD and the wider community. This is a place for students and faculty of the program to collaborate and develop a shared set of resources pertaining to the program, but we welcome contributions from anybody via pull request!
+Created by students of the [UCSD Bioinformatics and Systems Biology / Biomedical Informatics (BISB/BMI) PhD program](https://bioinformatics.ucsd.edu/), this organization serves as a place where students and faculty of the BISB/BMI program can collaborate and develop ...
+
+1. resources pertaining to the PhD program
+2. guidelines and executable tutorials for comptutional biology and bioinformatics workflows (we welcome contributions from *anybody* via pull request!)
+
+With these materials, we hope the organization will support computational biology and bioinformatics at UC San Diego and the wider community.
