Update README.md

Updated installation instructions via composer to use the `composer require` command without specifying a version.
This is the new recommended way of providing this information and it leads to composer picking the proper version constraint (i.e ~1.2), updating the `composer.json` and running install, all in one command.
supported add:task task.
changed name strategy in task and others.

- devide options from taskList.
supported task doc comment to usage.
