How to connected to existing MySQL database in Laravel 5?

I'm building a web application using Laravel 5. The tutorial I followed started with no data.

1. Create migrate table.

   It uses:

   php artisan make:migration create_table-name_tables --create="table_name"
   

2. Set up schema

   Then set up table schema in /database/migrations/_create_table-name_tables.php .

3. Perform migration: php artisan migrate.

4. Seeders.

   Create /database/seeds/table-nameTableSeeder.php. In this file there is actual rows in the table defined.

5. Add seed class to /database/seeds/DatabaseSeeder.php:

   use Illuminate\Database\Seeder;
   use Illuminate\Database\Eloquent\Model;
   
   class DatabaseSeeder extends Seeder {
   /**
    * Run the database seeds.
    *
    * @return void
    */
   public function run()
   {
       Model::unguard();
   
       $this->call('Table-nameTableSeeder');       
   }
   
   }
   

6. Seed with:

   composer dump-autoload
   php artisan db:seed
   

   My question: If I already have a existing database. How do I modify migration steps to use my database? Do I just need to do step 1,2 and 3? Then I can move on to Creating models?

Thanks in advance!
