A single page overview that walks a senior engineer from first install to a production-grade SaaS handoff. If you only read one Claude Code article, read this one; every other page under /claude-code expands a section of this guide.

Install the CLI, create a CLAUDE.md with your stack, add a .claude/settings.json with hooks for lint, test and format. Spend 30 minutes here. The agent quality on day 1 is directly proportional to the time invested on these three files.
Start with the smallest vertical slice that proves the product: auth, one real entity, the happy path. Let Claude Code scaffold the backend and the front-end together. Review every PR: you are the architect, the agent is the hand.
Add observability (logs, metrics, alerts), rate limiting, error handling and retries. Wire CI/CD with hooks so the agent can only merge when tests and lint are green. Generate docs as you go.
Claude Code writes the README, the runbook and the migration guide better than you would. Before handoff, run a security review (we use /security-review) and ship a list of outstanding TODOs as issues. Clients trained on Copilot can keep iterating after handover.
Two to four weeks for a focused B2B SaaS with one engineer. Our record is eight days from zero to paying customer. Scope discipline matters more than hours logged.
