-### 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.
-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，更主要的是可用于执行图的查询及分析操作。
+Gremlin can be used to create entities (Vertex and Edge) of a graph, modify
the properties of entities, and delete entities. More importantly, it can be
used to perform graph querying and analysis operations.
