+# EMQX OpenTSDB Bridge
 
-An OTP application
+[OpenTSDB](http://opentsdb.net) is a distributed, scalable Time Series Database (TSDB) written on top of HBase.
 
-Build
------
+OpenTSDB was written to address a common need: store, index and serve metrics collected from computer systems (network gear, operating systems, applications) at a large scale, and make this data easily accessible and graphable.
 
-    $ rebar3 compile
+OpenTSDB allows you to collect thousands of metrics from tens of thousands of hosts and applications, at a high rate (every few seconds). 
+
+OpenTSDB will never delete or downsample data and can easily store hundreds of billions of data points.
+
+The application is used to connect EMQX and OpenTSDB. User can create a rule and easily ingest IoT data into OpenTSDB by leveraging the
+[EMQX Rules](https://docs.emqx.com/en/enterprise/v5.0/data-integration/rules.html).
+
+
+# Documentation
+
+- Refer to [EMQX Rules](https://docs.emqx.com/en/enterprise/v5.0/data-integration/rules.html)

+  update bridge, get bridge, stop or restart bridge and list bridges etc.
