The README links a public place to ask a question and report a problem
A reader who is stuck either finds the channel or leaves. A private mailbox or a chat platform that needs an account and a client is not a channel, because the next person with the same question cannot find the answer you already wrote.
Observable check
README.md links at least one public channel that is searchable, addressable by URL, and usable without proprietary client software, covering both questions and defect reports; one channel satisfies both when the project routes them to the same place.
