Hi all,

I'm new in Symfony framework. I'm struggling now with Migrations event 
subscriber. I can't find any documentation explaining how to configure 
services. For this particular example I'm doing something like this:

//services.yaml

App\EventSubscribers\MigrationBugEvSubscriber:
         tags:
             - { name: ????, ????? }

Going through the Google, I tried to figure out how to get information 
about tag content: name of the Doctrine Migrations Bundle events and all 
other parameters. Official documentation says nothing:

https://symfony.com/doc/current/bundles/DoctrineMigrationsBundle/index.html

https://www.doctrine-project.org/projects/doctrine-migrations/en/2.1/reference/events.html

In the future I will use much more bundles with its own events. Could 
you explain how to generally make the events available and how to find 
documentation?

...or maybe configuring events support via services.yaml is obsolete?

Marek
