 The graph algorithm library running on Kunpeng processors is an acceleration library that provides a rich set of high-level tools for graph algorithms. It is developed based on original APIs of Apache [Spark 2.4.6](https://github.com/apache/spark/tree/v2.4.6). The acceleration library greatly improves the computing power in big data scenarios. Additionally, it provides multiple APIs in addition to the original APIs if the Apache Spark graph library.
 
-The library provides 23 graph algorithms: triangle count (TC), weak clique enumeration (WCE), maximal clique enumeration (MCE), modualrity, closeness, cycle detection (CD), label propagation algorithm (LPA), Louvain, PageRank, IncPageRank, Weighted PageRank, shortest-paths, strongly connected components (SCC), connected components (CC), K-core decomposition (KCore), degree centrality (Degree), breadth-first-search (BFS), ClusteringCoefficient, TrustRank, PersonalizedPageRank, Betweenness, Node2Vec and SubgraphMatching. You can find the latest documentation on the project web page. This README file contains only basic setup instructions.
