-TDengine is a high-efficient, scalable, high-available distributed time-series database, which makes a lot of optimizations on inserting and querying data, which is far more efficient than normal regular databases. So TDengine can meet the high requirements of IOT and other areas on storing and querying a large amount of data. 
+TDengine is an open-source, cloud-native time-series database optimized for Internet of Things (IoT), Connected Cars, and Industrial IoT. With its built-in caching, stream processing, and data subscription capabilities, TDengine offers a simplified solution for time-series data processing.
 
 TDengine will be installed under C:\TDengine, users can modify configuration file C:\TDengine\cfg\taos.cfg, set the log file path or other parameters.
 To start/stop TDengine with administrator privileges:  sc start/stop taosd
