Laravel 5.4 Route with Request and Params

I found myself stuck or lost in docs!

I'm using Laravel 5.4 and I'm trying to create validation in a controller which requires a request object.

My problem is my route passes parameters, I can't find in the docs an example how you include the Request $request argument and the $id parameter in a Controller method.

Here is my example:

1: SomeController.php

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
...
public function edit($id) {
    $request = Request; // <-- Do I use that instead of passing an arg?
}

2: Routes with a Paramter in -- routes/web.php

Route::match(['GET', 'POST'], '/some/edit/{id}', 'SomeController@edit');

In their example @ http://ift.tt/2mg9bj1 they have Request $request this in their controller, but what happens to Route parameters?:

public function store(Request $request) {}

---

Question: Do I need to edit the route or is the first parameter ignored if its a request?

---

A: Or would I do this in **SomeController.php?**

public function edit(Request $request, $id)
{
    // I would get the $request, but what happens to $id?
    $this->validate($request, [
        'title' => 'required|unique:posts|max:255',
    ]);
}

B: Perhaps, something like this?:

public function edit($id)
{
    // Or Request::getInstance()?
    $this->validate(Request, [
        'title' => 'required|unique:posts|max:255',
    ]);
}

Any advice would help, or even an example!
