+This repositry create a custom Node-Red node for configing TDEngine server connection and execute SQL from preview node msg.payload
+## Design
+Use Taos data restful API to commit SQL, API call like
+```
+curl -H 'Authorization: Basic <TOKEN>' -d '<SQL>' <ip>:<PORT>/rest/sql/[db_name]
+```
+
+Input options:
+* DB Server: Setup server connection or select a exist server
+* DB Name: Database to execute SQL
+
+Use [axios](https://axios-http.com/) to call http request
+
+## Usage
+
+1. Start Node-Red
+2. Install TDEngine node
+3. Add "taos query" node to workspace from palette 
+4. Setup a TDEngine server and database name
+5. Add function or other node to create SQL, put SQL into msg.payload
+6. Link to "taos query" node
+
+### Demo
+1. Start Node-Red by docker
+```
+docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red
+```
+2. Import sample flow "demo/flow.json"
+![import-flow](demo/ImportFlow.png)
+3. Install TDEngine node by name "node-red-contrib-tdengine", current version is 0.0.2
+![alt](demo/InstallTDEngineNode.png)
+4. Modify your TDEngine server config
+![alt](demo/ModifyServerConfig.png)
+5. Edit test SQL
+![alt](demo/EditTestSQL.png)
+6. Start flow by click Inject node
