Add Documentation on how-to add custom RoboTasks or DeployTasks

[mwr]

Per project one might have to have to customize exsting tasks or add additional tasks.

There needs to be some documentation on how to create local tasks beneath a src dir. Furthermore some doc on how to include tasks using composer might be helpful as well.

Any informal docs to this, I want to import a database from n98-magerun2.phar db:dump to the database before installing magento.

There are no docs available right now on how to do this. If you want to import that dump on the database that is created on the build-system then you would have to create a RoboTask that gets executed while the magento-setup stage. A tutorial on how to create tasks for robo can be found here: http://robo.li/getting-started/ If you want to import a dump on the database of your deploy-target then you would need to extend the deployer scripts by adding a command to the pipeline in deploy.php. Here is a link to the deployer documentation: https://deployer.org/docs/tasks
