 ## Usage
 
 Create a new graph
 
-    graph = Graph.new
+    graph = Solve::Graph.new
 
 Add an artifact to the graph
 
     graph.artifact("nginx", "1.0.0")

     graph.artifact("ntp", "1.0.0").depends("build-essential").depends("yum")
 
 And now solve the graph with some demands
 
-    Solve.it!(graph, ['nginx', '>= 0.100.0'])
+    Solve.it!(graph, [['nginx', '>= 0.100.0']])
 
 Or, if you want a topologically sorted solution
 NOTE: This will raise Solve::Errors::UnsortableSolutionError if the solution contains a cycle (which can happen with ruby packages)
 
-    Solve.it!(graph, ['nginx', '>= 0.100.0'], sorted: true)
+    Solve.it!(graph, [['nginx', '>= 0.100.0']], sorted: true)
 
 ### Increasing the solver's timeout
 
-By default the solver will wait 10 seconds before giving up on finding a solution. Under certain conditions a graph may be too complicated to solve within the alotted time. To increase the timeout you can set the "SOLVE_TIMEOUT" environment variable to the amount of seconds desired.
