How do I delete or update my pool metadata?

Removing metadata from the registry is an ad-hoc process. If this was allowed without verification, anyone could delete anyone's metadata.

I need to update my metadata and my private/public owner keys are the same.

In this case, the procedure is the same as for registering new metadata:

• Update your JSON file
• Produce a new signature that will replace the existing one
• Submit a pull request

I need to register different private/public owner keys but I want to keep the same ticker.

Here, you must make two pull requests:

PR A

• Update previous registration ticker to VOID + a number that isn't currently taken (e.g. VOID2).
• Produce a new signature to replace the existing one
• Submit a pull request
• Make sure to indicate your previous PR as a comment and explicitly mention that you are voiding this registration and want that registration deleted.

PR B

• Create a new registration re-using your previous ticker
• Name it after your new public key
• Submit a pull request
• Make sure to mention your "void PR" as a comment for reference.

note: PR B will fail to pass CI until the first one is merged. This is normal.
