## ADDED Requirements

### Requirement: Quick-start guide exists at docs/developers/quick-start.md
The system SHALL provide a quick-start guide at `docs/developers/quick-start.md` that enables a bedroom developer to register their first agent and issue an OAuth 2.0 access token in under 5 minutes.

#### Scenario: Developer completes quick-start from zero
- **WHEN** a developer with no prior AgentIdP knowledge follows the quick-start guide
- **THEN** they SHALL have a registered agent, a valid credential, and a working access token by the end

### Requirement: Quick-start lists exact prerequisites
The quick-start guide SHALL list all prerequisites at the top before any steps, so the developer knows what they need before starting.

#### Scenario: Prerequisites are minimal and explicit
- **WHEN** the developer reads the prerequisites section
- **THEN** they SHALL see exactly: Docker (for running PostgreSQL and Redis) and curl (for API calls) — nothing else required

### Requirement: Quick-start provides a working docker-compose startup command
The quick-start guide SHALL include a single command to start the required infrastructure (PostgreSQL + Redis) using the project's `docker-compose.yml`.

#### Scenario: Developer starts infrastructure
- **WHEN** the developer runs the provided docker-compose command
- **THEN** the guide SHALL confirm what services are started and what ports they run on

### Requirement: Quick-start covers the full 4-step workflow
The quick-start guide SHALL cover exactly these four steps in order, each with a working curl command and the expected response:

1. Start the AgentIdP server
2. Register an agent (`POST /agents`)
3. Generate a credential (`POST /agents/{agentId}/credentials`)
4. Issue an access token (`POST /token`)

#### Scenario: Each step has a copy-pasteable curl command
- **WHEN** the developer reads any step
- **THEN** they SHALL find a complete curl command with real placeholder values they can substitute

#### Scenario: Each step shows the expected JSON response
- **WHEN** the developer runs a curl command from the guide
- **THEN** the guide SHALL show them what a successful response looks like so they can verify their output

### Requirement: Quick-start ends with a next-steps section
The quick-start guide SHALL end with a "What's Next" section linking to: core-concepts.md, developer-guides.md, and api-reference.md.

#### Scenario: Developer knows where to go after quick-start
- **WHEN** the developer reaches the end of the quick-start
- **THEN** they SHALL see at least 3 links to deeper documentation
