有没有doctrine yaml定义数据库shema的比较详尽的文档？

比如symfony2中的例子:

Ens\JobeetBundle\Entity\CategoryAffiliate:
  type: entity
  table: category_affiliate
  id:
    id:
      type: integer
      generator: { strategy: AUTO }
  manyToOne:
    category:
      targetEntity: Category
      inversedBy: category_affiliates
      joinColumn:
        name: category_id
        referencedColumnName: id
    affiliate:
      targetEntity: Affiliate
      inversedBy: category_affiliates
      joinColumn:
        name: affiliate_id
        referencedColumnName: id

比较详尽的解释如generator这个option，以及manyToOne和OneToMany的option的文档
doctrine官网我找到的并不太清楚
