 ## Como rodar
 
-### Desenvolvimento (interativo)
+O script `start.sh` permite iniciar cada nó com o protocolo de distribuição desejado: **TCP** (padrão Erlang) ou **QUIC** (RFC 9000, via [erlang_quic](https://github.com/benoitc/erlang_quic)).
+
+### Pré-requisitos para QUIC
+
+Gere os certificados TLS (necessários apenas uma vez):
+
+```bash
+cd certs && bash generate.sh
+```
+
+### Usando o start.sh
+
+```bash
+# TCP (padrão)
+./start.sh --node http                    # nó HTTP na porta 8080
+./start.sh --node shell                   # nó Shell
+./start.sh --node default                 # ambos os apps no mesmo nó
+
+# QUIC
+./start.sh --node http --protocol quic    # nó HTTP com distribuição QUIC (porta dist 4434)
+./start.sh --node shell --protocol quic   # nó Shell com distribuição QUIC (porta dist 4435)
+./start.sh --node default --protocol quic # ambos os apps com QUIC (porta dist 4433)
+```
+
+Cada tipo de nó usa uma porta QUIC diferente para evitar conflito no mesmo host:
+
+| Nó | Porta QUIC |
+|----|------------|
+| default | 4433 |
+| http | 4434 |
+| shell | 4435 |
+
+> **Importante:** Todos os nós do cluster devem usar o mesmo protocolo. Nós QUIC e TCP não se conectam entre si.

+### Nomes de nós e cookie
 
 - Nó único: `config/dev_vm.config` (ex.: `-name rpc_server@127.0.0.1`, cookie `service_discovery_cookie`).
 - HTTP: `config/dev_http.vm.args` (ex.: `-name rpc_server_http@127.0.0.1`).
