-S2Graph [![Build Status](https://travis-ci.org/apache/incubator-s2graph.svg?branch=master)](https://travis-ci.org/apache/incubator-s2graph)  
-=======  
-  
-[**S2Graph**](http://s2graph.apache.org/) is a **graph database** designed to handle transactional graph processing at scale. Its REST API allows you to store, manage and query relational information using **edge** and **vertex** representations in a **fully asynchronous** and **non-blocking** manner.   
-  
-S2Graph is a implementation of [**Apache TinkerPop**](https://tinkerpop.apache.org/) on [**Apache HBASE**](https://hbase.apache.org/).   
-  
-This document covers some basic concepts and terms of S2Graph as well as help you get a feel for the S2Graph API.  
-  
-Building from the source  
-========================  
-  
-To build S2Graph from the source, install the JDK 8 and [SBT](http://www.scala-sbt.org/), and run the following command in the project root:  
-  
- sbt package  
-This will create a distribution of S2Graph that is ready to be deployed.  
-  
-One can find distribution on `target/apache-s2graph-$version-incubating-bin`.  
-  
-Quick Start  
-===========  
-  
-Once extracted the downloaded binary release of S2Graph or built from the source as described above, the following files and directories should be found in the directory.  
-

-  
-This directory layout contains all binary and scripts required to launch S2Graph. The directories `logs` and `var` may not be present initially, and are created once S2Graph is launched.  
-  
-The following will launch S2Graph, using [HBase](https://hbase.apache.org/) in the standalone mode for data storage and [H2](http://www.h2database.com/html/main.html) as the metadata storage.

- sh bin/start-s2graph.sh
