Doubts about the official website tutorial

[ChenKun1997]

After I run hexo init, the project is directly installed dependencies, no need to run npm install, right? There are also project dependencies installed. There is a yarn.lock file in the root directory. Obviously, the project uses yarn. Why do you guide users to use npm to install it? Why not yarn？（forgive my bad english）

Because npm is usually installed alongside with node.js, while yarn is installed manually. When Hexo finds that yarn is installed, it guesses that you prefer yarn so it uses yarn.
