Link is broken

On this page. link of "Service Contracts - Data interfaces" is broken

It just sends to main developer doc page.

i suggest replace

http://devdocs.magento.com/guides/v2.0//extension-dev-guide/service-contracts/design-patterns.html#data-interfaces

with

http://devdocs.magento.com/guides/v2.0/extension-dev-guide/service-contracts/design-patterns.html#data-interfaces

There's a extra "/" after v2.0
