 ### Collection verification
 
-Note that there is no such thing as compressed Verified Collections.  Collections are still NFTs created in the realm of Metadata and Master Edition `token-metadata` accounts. There are instructions to `verify_collection` and `unverify_collection`, as well as a `set_and_verify_collection` instruction for the case where the collection was set during the mint. `mint_to_collection_v1` is an instruction can be used to mint and verify a collection at the same time. Currently `decompress_v1` will fail for verified collection compressed assets, and will only be successful for unverified / no collection compressed assets. The complete flow for decompressing a verified asset would be to unverify its collection, decompress, and reverify collection through traditional means.
-All of these require either the true Collection Authority to be a a signer, or a delegated Collection Authority to be a signer along with providing a Collection Authority Record PDA.  See the Metaplex documentation on [`Certified Collections`](https://docs.metaplex.com/programs/token-metadata/certified-collections) for more information on verifying collections.
