+    """The GAP Benchmark Suite is intended to help graph processing research by
+    standardizing evaluations. Fewer differences between graph processing
+    evaluations will make it easier to compare different research efforts and
+    quantify improvements. The benchmark not only specifies graph kernels,
+    input graphs, and evaluation methodologies, but it also provides an
+    optimized baseline implementation (this repo). These baseline
+    implementations are representative of state-of-the-art performance, and
+    thus new contributions should outperform them to demonstrate an
+    improvement."""
