Install via composer - In the terminal:

composer require bigbeartech/attachments

Now add the following to the providers array in your config/app.php

BigBearTech\Attachments\AttachmentsServiceProvider::class,

and this to the aliases array in config/app.php

"Attachment" => "BigBearTech\Attachments\Facades\Attachment",

Then you will need to run these commands in the terminal in order to copy the config and migration files

php artisan vendor:publish --provider="BigBearTech\Attachments\AttachmentsServiceProvider"

Before you run the migration you may want to take a look at config/attachments.php and change the table property to a table name that you would like to use. After that run the migration

php artisan migrate
