            "bower-asset-library": "vendor/bower"
        }
    },
}

I need it to be installed not in leopandro/yii2-soft but in dektrium/yii2-soft. How to do it? I did not find a single example on the Internet, only dry documentation in English.
Tried like this:

"name":{
        "name": "dektrium/yii2-user"
    },
    "replace":{
        "Leopandro/yii2-user":"dev-master"
    }

just fork the project and create a packagist at packagist.org/packages/kak/
