<project name> is optional. If it isn't set then:

1. If a current directory contains existing Yarn project (contains package.json and yarn.lock; NPM projects aren't supported) then:

   • If a project is Yarn 1 then it will be upgraded to Yarn 2.

   • If a project already is Yarn 2 then it will be adjusted.

2. If package.json isn't found in a current directory then a new Yarn 2 project will be created.

--overwrite-config-files is optional and will enforce overwriting of all dependencies config files (.babelrc, .eslintrc, .gitignore etc.)
