+# Framework Integrations
+
+TypeID is designed to be framework-agnostic.
+The core package does not depend on any web framework, ORM, or serialization library.
+
+Integrations are provided as **optional** adapters that translate between TypeID and specific ecosystems.
+They are installed explicitly and never affect the core unless imported.
+
+---
+
+## Available integrations
+
+### Pydantic (v2)
+
+Native support for using TypeID in Pydantic v2 models.
+
+* Prefix-aware validation
+* Accepts `str` and `TypeID`
+* Serializes as string
+* Clean JSON Schema / OpenAPI output
+
+```bash
+pip install typeid-python[pydantic]
+```
+
+See: [Pydantic v2](https://akhundmurad.github.io/typeid-python/integrations/pydantic/) documentation page for details and examples.
+
+### FastAPI
+
+FastAPI builds on Pydantic v2, so TypeID works automatically in:
+
+* request models
+* response models
+* OpenAPI schemas
+
+No separate FastAPI-specific adapter is required.
+
+```bash
+pip install typeid-python[fastapi]
+```
+
+See: [Pydantic v2](https://akhundmurad.github.io/typeid-python/integrations/fastapi/) documentation page for details and examples.
+
+### SQLAlchemy
+
+Column types for storing TypeIDs in relational databases.
+
+Typical usage stores the full TypeID string (`prefix_suffix`) for clarity and debuggability.
+
+```bash
+pip install typeid-python[sqlalchemy]
+```
+
+See: [Pydantic v2](https://akhundmurad.github.io/typeid-python/integrations/sqlalchemy/) documentation page for details and examples.
+
+## Design notes
+
+* The TypeID core never imports framework code
+* Validation rules live in the core, not in adapters
+* Integrations are thin and easy to replace or extend
+
+This keeps the library stable even as frameworks evolve.
+
+## Adding new integrations
+
+If you want to integrate TypeID with another framework:
+
+* keep the adapter small,
+* avoid duplicating validation logic,
+* depend on the TypeID core as the single source of truth.
+
+Community integrations are welcome.

+# Pydantic v2 integration
+
+TypeID ships with an **optional Pydantic v2 adapter**.
+It lets you use `TypeID` in Pydantic models without pulling Pydantic into the TypeID core.
+
+The adapter:
+
+* validates values using the TypeID core,
+* optionally enforces a fixed prefix,
+* serializes TypeIDs as strings,
+* exposes sensible JSON Schema metadata.
+
+---
+
+## Installation
+
+```bash
+pip install typeid-python[pydantic]
+```
+
+This installs the latest version of Pydantic v2.
+
+## Basic usage
+
+Use `TypeIDField` with a fixed prefix.
+
+```python
+from typing import Literal
+from pydantic import BaseModel
+from typeid.integrations.pydantic import TypeIDField
+
+class User(BaseModel):
+    id: TypeIDField[Literal["user"]]
+
+u = User(id="user_01ke82dtesfn9bjcrzyzz54ya9")
+assert str(u.id) == "user_01ke82dtesfn9bjcrzyzz54ya9"
+```
+
+## Accepted inputs
+
+You can pass either a string or a `TypeID` instance.
+
+```python
+from typing import Literal
+from pydantic import BaseModel
+from typeid.integrations.pydantic import TypeIDField
+
+class User(BaseModel):
+    id: TypeIDField[Literal["user"]]
+
+u = User(id="user_01ke82dtesfn9bjcrzyzz54ya9")
+assert u.id is not None
+```
+
+```python
+from typing import Literal
+from pydantic import BaseModel
+from typeid import TypeID
+from typeid.integrations.pydantic import TypeIDField
+
+class User(BaseModel):
+    id: TypeIDField[Literal["user"]]
+
+tid = TypeID.from_string("user_01ke82dtesfn9bjcrzyzz54ya9")
+u = User(id=tid)
+
+assert u.id == tid
+```
+
+In both cases, `id` is stored as a `TypeID` object inside the model.
+
+## Prefix validation
+
+The prefix in `TypeIDField[...]` is enforced.
+
+```python
+import pytest
+from typing import Literal
+from pydantic import BaseModel, ValidationError
+from typeid.integrations.pydantic import TypeIDField
+
+class Order(BaseModel):
+    id: TypeIDField[Literal["order"]]
+
+with pytest.raises(ValidationError):
+    Order(id="user_01ke82dtesfn9bjcrzyzz54ya9")
+```
+
+This fails with a validation error because the prefix does not match.
+
+This is useful when you want the model itself to encode domain meaning
+(e.g. *this field must be a user ID, not just any ID*).
+
+## Serialization
+
+When exporting a model, TypeIDs are always serialized as strings.
+
+```python
+from typing import Literal
+from pydantic import BaseModel
+from typeid.integrations.pydantic import TypeIDField
+
+class User(BaseModel):
+    id: TypeIDField[Literal["user"]]
+
+u = User(id="user_01ke82dtesfn9bjcrzyzz54ya9")
+data = u.model_dump(mode="json")
+
+assert data == {"id": "user_01ke82dtesfn9bjcrzyzz54ya9"}
+```
+
+```python
+from typing import Literal
+from pydantic import BaseModel
+from typeid.integrations.pydantic import TypeIDField
+
+class User(BaseModel):
+    id: TypeIDField[Literal["user"]]
+
+u = User(id="user_01ke82dtesfn9bjcrzyzz54ya9")
+json_data = u.model_dump_json()
+
+assert json_data == '{"id":"user_01ke82dtesfn9bjcrzyzz54ya9"}'
+```
+
+This keeps JSON output simple and predictable.
+
+## JSON Schema / OpenAPI
+
+The generated schema looks roughly like this:
+
+```yaml
+id:
+  type: string
+  format: typeid
+  description: TypeID with prefix 'user'
+  examples:
+    - user_01ke82dtesfn9bjcrzyzz54ya9
+```
+
+Notes:
+
+* The schema does not hard-code internal regex details.
+* Actual validation is handled by the TypeID core.
+* The schema is meant to document intent, not re-implement parsing rules.
+
+## Why `Literal["user"]`?
+
+The recommended form is:
+
+```text
+TypeIDField[Literal["user"]]
+```
+
+This works cleanly with:
+
+* Ruff
+* Pyright / MyPy
+* IDE type checkers
+
+Using `Literal` makes the prefix a real compile-time constant and avoids
+annotation edge cases.
+
+## FastAPI
+
+FastAPI uses Pydantic v2, so no extra integration is needed.
+
+TypeID fields work automatically in request and response models,
+including OpenAPI output, as soon as you use them in a Pydantic model.
+
+## Design notes
+
+* The TypeID core does not import Pydantic.
+* All framework-specific code lives in `typeid.integrations.pydantic`.
+* Parsing and validation rules live in the core, not in the adapter.
+
+This keeps the integration small and easy to maintain.
+
+*That’s it — no magic, no hidden behavior.*
