How do I successfully verify my site for Baidu's webmaster tools?

[sigmaaldrich]

Instructions for verifying a website via file validation for Baidu's webmaster tools are pretty vague. Does anyone know if the process is the same as Google Webmaster Tools where the verification string must appear in the URL and in the content of the file? Also, does it truly have to be verified within 2.6 hours? Appreciate any feedback from people who have successfully verified their site.
