 understand your repository and its tasks. A graph is made up of "nodes" and
-"edges". In our Task Graph, the nodes are tasks and the edges are the the
+"edges". In our Task Graph, the nodes are tasks and the edges are the
 dependencies between tasks. A _directed_ graph indicates that the edges
 connecting each node have a direction, so if Task A points to Task B, we can say
 that Task A depends on Task B. The direction of the edge depends on which task
