## Installing DevEco Device Tool
DevEco Device Tool is installed in Visual Studio Code as a plug-in and depends on Python, Node.js, and HPM for running.
DevEco Device Tool supports integrated installation. The DevEco Device Tool setup wizard checks whether the adaptation versions of Visual Studio Code, Python, Node.js and HPM tools have been installed. If any of the tools is not installed, you'll be prompted to select the tool to be automatically installed.
