 ## Quick Install
 
-The full package of TDengine includes the server(taosd), taosAdapter for connecting with third-party systems and providing a RESTful interface, client driver(taosc), command-line program(CLI, taos) and some tools. For the current version, the server taosd and taosAdapter can only be installed and run on Linux systems. In the future taosd and taosAdapter will also be supported on Windows, macOS and other systems. The client driver taosc and TDengine CLI can be installed and run on Windows or Linux. In addition to connectors for multiple languages, TDengine also provides a [RESTful interface](/reference/rest-api) through [taosAdapter](/reference/taosadapter). Prior to version 2.4.0.0, taosAdapter did not exist and the RESTful interface was provided by the built-in HTTP service of taosd.
