Installation instructions should be improved
The meaning of the different entries in .env.example should either be explained in the README or in the example file itself.
APP_URL seem to be essential to make a Cosum installation run.
php artisan key:generate
should be added to the "Database" section in order to generate an APP_KEY.
In section "The first User" parameters for
App\\User::create should be added. As far as I can tell, this should work
$u1=App\User::create(['name'=>'admin', 'email'=>'email@example.com', 'admitted'=>1, 'password'=>bcrypt('theAdminPW')]);
Furthermore, it would be better to have the statements required in this section to be put in a block in order to not miss one of them.
