 # TritonRoute
 **TritonRoute** is an open source detailed router for modern industrial 
 designs. The router consists of several main building blocks, including 
-track assignment, initial detailed routing, search and repair, and a DRC 
-engine.  The initial development of the 
+pin access analysis, track assignment, initial detailed routing, 
+search and repair, and a DRC engine. The initial development of the 
 [router](https://vlsicad.ucsd.edu/Publications/Conferences/363/c363.pdf) 
 is inspired by the 
 [ISPD-2018 initial detailed routing contest](http://www.ispd.cc/contests/18/).
