How to install it and include Wkhtmltopdf in Yii2

I want to convert my HTML file to PDF. I Heard about tcpdf, and i have succesfully installed with composer : "cinghie/yii2-tcpdf": "dev-master"

But a lot of limitation of TCPDF makes me want to try WKHTMLTOPDF, but i get confused in installation and including in my view file. I’ve tried with this:

"mikehaertl/phpwkhtmltopdf": "2.0.*@dev"

but i still can’t include it in view files.

Hope Someone can help me.

Thanks in advance
