No query results for model [RampUp\Skills].

Whenever I try to access /skills/add I get

No query results for model [RampUp\Skills].

Tried using dd("test") but won't even appear

This are my routes for skills/add

Route::put('/skills/add', 'SkillsController@add');

Route::get('/skills/add', 'SkillsController@addIndex');

Here are my functions in SkillsController

public function addIndex() {
        if (Auth::check()) {
            return view('skills.add');
        } else {
            return redirect('/home');
        }
    }

and

public function add(Request $request) {
        /*Sets validation rules for Skill object*/
        $skillRules = [
            'name' => 'required|max:25|regex:/[1-9a-zA-Z ]\w*/',
        ];
        if (Skills::where('name', '=', $request->name)->count() > 0) {
            return redirect('/skills')->with('message', "EXISTS");
        }

        $validator = Validator::validate($request->all(), $skillRules);
        if ($validator == null) {
            $newSkill = new Skills;
            $newSkill->name = strtolower($request->name);
            $newSkill->save();
            return redirect('/skills')->with('message', "CREATED");
        }
    }

the skills.add view is this

@extends('layouts.app')

@section('content')

<div class="container">
    <h1>Edit Skill</h1>
    <form method="POST" action="/skills/add">
        {{method_field('PUT')}}
