        ["type", "connect"]
    ]
}

    "tags": [
        ["type", "disconnect"]
    ]
}

Used when responding to a type:connect. Offering to connect to that peer.

{
    "kind": 25050,
    "pubkey": "<sender pubkey>",
    "tags": [
        ["type", "offer"],
        ["p", "<reciever pubkey>"]
    ],
    "content": {
        "offer": "<offer>",
        "type": "offer"
    }
}

Answering an Offer

{
    "kind": 25050,
    "pubkey": "<sender pubkey>",
    "tags": [
        ["type", "answer"],
        ["p", "<reciever pubkey>"]
    ],
    "content": {
        "sdp": "<sdp>",
        "type": "answer"
    }
}

Broadcasting ICE Candidate

{
    "kind": 25050,
    "pubkey": "<sender pubkey>",
    "tags": [
        ["type", "answer"],
        ["p", "<reciever pubkey>"]
    ],
    "content": {
        "candidate": "<sdp>",
        <misc>
    }
}

Essentially, just directly feed what comes out of the WebRTC functions straight into the content field. It makes things cleaner and easier.
