Package not found from vcs repo - composer-php

Question

I have forked a repo and created a branch called 3.0 that I would like to install to my project to test (not a longterm fork. I want to create a pull request after testing). I have added the following to my composer file:
"repositories": [{
"type": "vcs",
"url": "https://github.com/albertski/laravel-grid"
}],
When running composer show "albertski/laravel-grid" I get Package albertski/laravel-grid not found.
When I run composer require albertski/laravel-grid:3
.0-dev I get the following:
Could not find a matching version of package albertski/laravel-grid. Check
the package spelling, your version constraint and that the package is avail
able in a stability which matches your minimum-stability (dev).
Am I missing any steps? According to the docs that should be it. I am using Composer version 1.9.0.
This is my full composer.json file:

]
},
"autoload-dev": {

},
"files": ["tests/utilities/functions.php"]
},
"minimum-stability": "dev",
"prefer-stable": true,
"scripts": {
"post-autoload-dump": [
"Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
"#php artisan package:discover --ansi"
],

"#php -r \"file_exists('.env') || copy('.env.example', '.env');\""
],
"post-create-project-cmd": [
"#php artisan key:generate --ansi"
]
}
}
Edit
Just to test it out I created a branch called 3.0_albert and updated the composer.json name field to "name": "albertski/laravel-grid",. (Not a fan of doing this because I eventually want to perform a pull request)
Then ran composer require albertski/laravel-grid:3.0_albert-dev but same issue.

Answer 1

I was able to figure it out. Instead of calling:
composer require albertski/laravel-grid:3.0.x-dev
You call:
composer require leantony/laravel-grid:3.0.x-dev
Basically by adding:
"repositories": [{
"type": "vcs",
"url": "https://github.com/albertski/laravel-grid"
}],
You are telling composer to check your repo first for the package instead of the default one.
