Connecting vuelidate to vue project without cli?

Question

Vue.js

Tell me, the question has been tormenting me for a long time, I still don’t really understand this. There are projects on assemblers like webpack, there is just a vue connection in a separate js file.
I have just the second option, I am doing a project on vue without the participation of npm cli. So here's how to properly connect vuelidate to the project in this case?
The project structure is as follows:
vue is connected in scripts,
the main.js script file is connected, it already contains

window.onload = function () {
    var app = new Vue({
        el: '#app',
        /*   Data   */
        data: {

and so on..
So I need to connect vuelidate, how to do it right?
