Setting up n8n and your API keys

We will self-host n8n with Docker — it takes one command — and wire in an LLM credential.

docker run -it --rm \
  --name n8n \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  docker.n8n.io/n8nio/n8n

Open http://localhost:5678, create your owner account, then add your API key under Credentials → OpenAI.
