@MythicalCow Can you please provide the source for the Mermaid diagram? GitHub allows you to render Mermaid diagrams inline with Markdown:

```mermaid
sequenceDiagram
  // Rest of diagram here

When you can, please commit the diagram into [misc_protocol.md](https://github.com/sigpwny/2024-ectf-uiuc/blob/main/docs/misc_protocol.md). I would also appreciate it if you could follow a similar syntax and style to the other diagrams.
