How do you validate a document? #214

Sorry I'm confused by https://github.com/Open-Attestation/open-attestation#verify-signature-of-document

Note that this method does not check against the blockchain or any registry if this document has been published. The merkle root of this document need to be checked against a publicly accessible document store (can be a smart contract on the blockchain).

How does one perform the "need to be checked against a publicly accessible document store"?

Hi, in order to perform the merkle root check, please use our sister library oa-verify.

In particular, the verifier needs to have the DOCUMENT_STATUS verifier. https://github.com/Open-Attestation/oa-verify#custom-verification
