 This repository is a Rust server that supports both contribution (ingest) and distribution (playback).
 It requires a client, such as [moq-js](https://github.com/kixelated/moq-js).
 
-## Requirements
+## Setup
 
--   **rust**: duh
+### Media
--   **ffmpeg**: (optional) used to generate fragmented media
--   **go**: (optional) used to generate self-signed certificates
--   **openssl**: (options) ...also used to generate self-signed certificates
-
-## Media
 
 This demo simulates a live stream by reading a file from disk and sleeping based on media timestamps. Obviously you should hook this up to a real live stream to do anything useful.
 
-Download your favorite media file and convert it to fragmented MP4, by default `media/fragmented.mp4`:

 ./media/generate
 ```
 
-## Certificates
+### Certificates
 
 Unfortunately, QUIC mandates TLS and makes local development difficult.
 If you have a valid certificate you can use it instead of self-signing.
 
-Otherwise, we use [mkcert](https://github.com/FiloSottile/mkcert) to install a self-signed CA:
+Use [mkcert](https://github.com/FiloSottile/mkcert) to generate a self-signed certificate.
+Unfortunately, this currently requires Go in order to [fork](https://github.com/FiloSottile/mkcert/pull/513) the tool.
 
 ```
 ./cert/generate
 ```
 
-With no arguments, the server will generate self-signed cert using this root CA.
+Unfortunately, WebTransport in Chrome currently (May 2023) doesn't verify certificates using the root CA.
-This certificate is only valid for _2 weeks_ due to how WebTransport performs certificate fingerprinting.
+The workaround is to use the `serverFingerprints` options, which requires the certificate MUST be only valid for at most **14 days**.
+This is also why we're using a fork of mkcert, because it generates certificates valid for years by default.
+This limitation will be removed once Chrome uses the system CA for WebTransport.
