-### 概述
+### Overview
-HugeGraph支持[Apache TinkerPop3](https://tinkerpop.apache.org)的图形遍历查询语言[Gremlin](https://tinkerpop.apache.org/gremlin.html)。 SQL是关系型数据库查询语言，而Gremlin是一种通用的图数据库查询语言，Gremlin可用于创建图的实体（Vertex和Edge）、修改实体内部属性、删除实体，也可执行图的查询操作。
+HugeGraph supports [Gremlin](https://tinkerpop.apache.org/gremlin.html), a graph traversal query language of [Apache TinkerPop3](https://tinkerpop.apache.org). While SQL is a query language for relational databases, Gremlin is a general-purpose query language for graph databases. Gremlin can be used to create entities (Vertex and Edge) of a graph, modify the properties of entities, delete entities, as well as perform graph queries.
