+# Install and Setup
+
+This document gives practical setup guidance for each supported client. Keep credentials and secret values out of the repository whenever possible.
+
+## Shared prerequisites
+
+Before setting up a client, make sure you have:
+- a working n8n instance
+- access to its MCP server or MCP-enabled endpoint
+- a client that supports MCP
+- a place to store client-level config and auth safely
+
+## Recommended setup pattern
+
+1. Configure the n8n MCP server in the client.
+2. Keep this repository in the working directory.
+3. Reference `templates/system-prompt.md` and `docs/conversation-contract.md`.
+4. Ask the agent to emit a normalized plan before it builds.
+5. Test with one recipe.

+
+## Secrets and auth
+
+Prefer one of these patterns:
+- client-managed OAuth flow
+- environment variables referenced by the client config
+- local machine secret manager
+
+Avoid putting raw secrets in:
+- repository-tracked JSON files
+- prompt templates
+- examples intended for public publication
