 ## geom2graph
 
-The `geom2graph` tool is the lone C++ tool in the project. It uses GEOS to convert back and forth
-between geometries and their graph representations (using a fuzzy tolerance, as well as duplicate
-node and overlapping edge detection).
+The `geom2graph` tool converts back and forth between geometries and their graph representations
+(using an optional fuzzy tolerance, as well as duplicate node and overlapping edge detection).
 
 That means you can go Geometry Collection -> Graph -> Geometry Collection to perform dramatic
 geometry simplification!
 
-**Note:** `geom2graph` only works in 2D, and does funky stuff with 3D geometries.
