Where should I put the NoPin on Pinterest metafield definition?

[ST20001]

I would like to disable pinning from my entire site, including all images.

I have the code: <meta name="pinterest" content="nopin" />

...and I believe it goes into the metafield area ( Settings > Custom Data )

What next?

Thank you.
