Laravel utilizes Composer to manage its dependencies. So, before using Laravel, make sure you have Composer installed on your machine.
install laravel
composer global require laravel/installer
put laravel into your path
echo 'export PATH=$HOME/.config/composer/vendor/bin/ :$PATH' >> ~/.bashrc
start laravel project
laravel new <projectname>
install dependencies
composer install composer update
rename env.example
mv .env.example .env
generate encryption key
php artisan key:generate
serve at localhost
php artisan serve
