Add public repository interfaces and subclassable adapter CRUD API.

Define split JSON and object repository ABCs, promote adapter methods to public CRUD, add example domain repositories, modernize interface stubs, and make the package installable for tests.

 # python-repositories
 
-Various python repository interfaces exposed as a python package.
+Unified repository interfaces and technology-specific adapters for Python projects.
+
+Subclass an adapter in your own repository to add domain-specific methods while reusing connection management and CRUD operations.
+
+## Architecture
+
+| Layer | Responsibility |
+|-------|----------------|
+| **Interfaces** | Abstract contracts for connection, context, and CRUD |
+| **Adapters** | Technology-specific base classes (`RedisAdapter`, `MinioAdapter`) |
+| **Your project** | Subclass an adapter and add domain methods |
 
 ## Optional dependencies
 
-This package supports interacting with multiple different backends:
+Install with the extras you need:
-
-- Redis
-- MinIO
-
-To add support for a specific backend install this package with one or more of these optional packages:
 
 ```bash
-uv add python-repositories[redis, minio]
+uv add python-repositories[redis]
+uv add python-repositories[minio]
+uv add python-repositories[redis,minio]
 ```
+
+### Redis (`JsonRepositoryInterface`)
+
+Requires Redis with the RedisJSON module (e.g. redis-stack).
+
+| Environment variable | Description |
+|---------------------|-------------|
+| `REDIS_URI` | Redis connection URL (e.g. `redis://localhost:6379`) |
+
+### MinIO (`ObjectRepositoryInterface`)
+
+| Environment variable | Description |
+|---------------------|-------------|
+| `MINIO_ENDPOINT` | MinIO server endpoint |
+| `MINIO_ACCESS_KEY` | Access key |
+| `MINIO_SECRET_KEY` | Secret key |
+| `MINIO_BUCKET` | Bucket name (created on connect if missing) |
+
+## Quick start
+
+### JSON documents with Redis
+
+```python
+from python_repositories.examples.user_json_repository import UserJsonRepository
+
+with UserJsonRepository() as repo:
+    repo.save_user("alice", {"name": "Alice", "email": "[email protected]"})
+    user = repo.get_user("alice")
+    repo.delete_user("alice")
+```
+
+### Binary objects with MinIO
+
+```python
+from io import BytesIO
+
+from python_repositories.examples.artifact_object_repository import (
+    ArtifactObjectRepository,
+)
+
+with ArtifactObjectRepository() as repo:
+    repo.store_artifact("report-1", BytesIO(b"pdf bytes here"))
+    data = repo.get_artifact("report-1")
+```
+
+### Subclassing in your own project
+
+```python
+from python_repositories import RedisAdapter
+
+class UserRepository(RedisAdapter):
+    def _key(self, user_id: str) -> str:
+        return f"user:{user_id}"
+
+    def get_user(self, user_id: str) -> dict | None:
+        return self.get(self._key(user_id))
+
+    def save_user(self, user_id: str, user: dict) -> None:
+        self.set(self._key(user_id), user)
+```
+
+## Public API
+
+```python
+from python_repositories import (
+    ConnectionAwareInterface,
+    ContextAwareInterface,
+    JsonRepositoryInterface,
+    ObjectRepositoryInterface,
+    RedisAdapter,
+    MinioAdapter,
+)
+```
+
+## Development
+
+```bash
+uv sync --all-extras
+uv run pytest tests/integration/ -v
+```
+
+Integration tests require Docker (testcontainers).
