During its lifetime, Symfony 2 has had two ways to install bundles: bin/vendors.php and Composer. And probably there will be another way to do it in the near future via thebundle:install command. Also, using Composer, there are several ways to do it:composer require, editcomposer.json, .phar/no .phar...

For bundle maintainers this is a problem, and from the point of view of the developer, can be confusing that instructions change from one bundle to another.

Proposal: Add a section in the symfony official documentation where, based on the Symfony version, provides all the instructions and alternatives to install any bundle. Then, the bundle maintainers can link to that page in our docs.
