 ## Usage
 
-`PDDLViz.jl` provides a number of built-in renderer types for certain classes of domains, such as [`GridworldRenderer`](test/gridworld/test.jl) or [`GraphworldRenderer`](test/graphworld/test.jl). Each renderer can be customized for a specific domain by passing in options to its constructor:
