+
+# Summary
+
+Mail Intake — provider-agnostic, read-only email ingestion framework.
+
+Mail Intake is a **contract-first library** designed to ingest, parse, and
+normalize email data from external providers (such as Gmail) into clean,
+provider-agnostic domain models.
+
+The library is intentionally structured around clear layers, each exposed
+as a first-class module at the package root:
+
+- `adapters`: Provider-specific access (e.g., Gmail).
+- `auth`: Authentication providers and credential lifecycle management.
+- `credentials`: Credential persistence abstractions and implementations.
+- `parsers`: Extraction and normalization of message content.
+- `ingestion`: Orchestration and high-level ingestion workflows.
+- `models`: Canonical, provider-agnostic data representations.
+- `config`: Explicit global configuration.
+- `exceptions`: Library-defined error hierarchy.
+
+The package root acts as a **namespace**, not a facade. Consumers are
+expected to import functionality explicitly from the appropriate module.
+
+---
+
+# Installation
+
+Install using pip:
+
+```bash
+pip install mail-intake
+```
+
+Or with Poetry:
+
+```bash
+poetry add mail-intake
+```
+
+Mail Intake is pure Python and has no runtime dependencies beyond those
+required by the selected provider (for example, Google APIs for Gmail).
+
+---
+
+# Quick Start
+
+Minimal Gmail ingestion example (local development):
+
+```python
+from mail_intake.ingestion import MailIntakeReader
+from mail_intake.adapters import MailIntakeGmailAdapter
+from mail_intake.auth import MailIntakeGoogleAuth
+from mail_intake.credentials import PickleCredentialStore
+
+store = PickleCredentialStore(path="token.pickle")
+
+auth = MailIntakeGoogleAuth(
+    credentials_path="credentials.json",
+    store=store,
+    scopes=["https://www.googleapis.com/auth/gmail.readonly"],
+)
+
+adapter = MailIntakeGmailAdapter(auth_provider=auth)
+reader = MailIntakeReader(adapter)
+
+for message in reader.iter_messages("from:recruiter@example.com"):
+    print(message.subject, message.from_email)
+```
+
+Iterating over threads:
+
+```python
+for thread in reader.iter_threads("subject:Interview"):
+    print(thread.normalized_subject, len(thread.messages))
+```
+
+---
+
+# Architecture
+
+Mail Intake is designed to be extensible via **public contracts** exposed
+through its modules:
+
+- Users MAY implement their own mail adapters by subclassing
+  `adapters.MailIntakeAdapter`.
+- Users MAY implement their own authentication providers by subclassing
+  `auth.MailIntakeAuthProvider[T]`.
+- Users MAY implement their own credential persistence layers by implementing
+  `credentials.CredentialStore[T]`.
+
+Users SHOULD NOT subclass built-in adapter implementations. Built-in
+adapters (such as Gmail) are reference implementations and may change
+internally without notice.
+
+**Design Guarantees:**
+
+- Read-only access: no mutation of provider state.
+- Provider-agnostic domain models.
+- Explicit configuration and dependency injection.
+- No implicit global state or environment reads.
+- Deterministic, testable behavior.
+- Distributed-safe authentication design.
+
+Mail Intake favors correctness, clarity, and explicitness over convenience
+shortcuts.
+
+**Core Philosophy:**
+
+`Mail Intake` is built as a **contract-first ingestion pipeline**:
+
+1. **Layered Decoupling**: Adapters handle transport, Parsers handle format
+   normalization, and Ingestion orchestrates.
+2. **Provider Agnosticism**: Domain models and core logic never depend on
+   provider-specific (e.g., Gmail) API internals.
+3. **Stateless Workflows**: The library functions as a read-only pipe, ensuring
+   side-effect-free ingestion.
+
+---
+
+# Public API
+
+The supported public API consists of the following top-level modules:
+
+- `mail_intake.ingestion`
+- `mail_intake.adapters`
+- `mail_intake.auth`
+- `mail_intake.credentials`
+- `mail_intake.parsers`
+- `mail_intake.models`
+- `mail_intake.config`
+- `mail_intake.exceptions`
+
+Classes and functions should be imported explicitly from these modules.
+No individual symbols are re-exported at the package root.
