-## Demo
+FastAPI OAuth2 is a middleware-based social authentication mechanism supporting several auth providers. It depends on
+the [social-core](https://github.com/python-social-auth/social-core) authentication backends.
 
-This sample application is made to demonstrate the use of the [**fastapi-oauth2**](./fastapi_oauth2) package.
+## Features to be implemented
 
-## Running the application
+- Use multiple OAuth2 providers at the same time
+    * There need to be provided a way to configure the OAuth2 for multiple providers
+- Provide `fastapi.security.*` implementations that use cookies
+- Token -> user data, user data -> token easy conversion
+- Customizable OAuth2 routes
+- Registration support
+
+## Installation
 
-```bash
-uvicorn main:app --reload
+```shell
+python -m pip install fastapi-oauth2
 ```
 
-## TODO
+## Configuration
 
-- Make the [**fastapi-oauth2**](./fastapi_oauth2) depend
-  on (overuse) the [**social-core**](https://github.com/python-social-auth/social-core)
+Configuration requires you to provide the JWT requisites and define the clients of the particular providers. The
+middleware configuration is declared with the `OAuth2Config` and `OAuth2Client` classes.
 
-## Features
+### OAuth2Config
 
-- Integrate with any existing FastAPI project (no dependencies of the project should stop the work of
-  the `fastapi-oauth2`)
-    * Implementation must allow to provide a context for configurations (also, see how it is done in another projects)
-- Use multiple OAuth2 providers at the same time
-    * There need to be provided a way to configure the OAuth2 for multiple providers
-- Token -> user data, user data -> token easy conversion
-- Customize OAuth2 routes
+- `allow_http` - Allow insecure HTTP requests. Defaults to `False`.
+- `jwt_secret` - The secret key used to sign the JWT. Defaults to `None`.
+- `jwt_expires` - The expiration time of the JWT in seconds. Defaults to `900`.
+- `jwt_algorithm` - The algorithm used to sign the JWT. Defaults to `HS256`.
+- `clients` - The list of the OAuth2 clients. Defaults to `[]`.
+
+### OAuth2Client
+
+- `backend` - The [social-core](https://github.com/python-social-auth/social-core) authentication backend classname.
+- `client_id` - The OAuth2 client ID for the particular provider.
+- `client_secret` - The OAuth2 client secret for the particular provider.
+- `redirect_uri` - The OAuth2 redirect URI to redirect to after success. Defaults to the base URL.
+- `scope` - The OAuth2 scope for the particular provider. Defaults to `[]`.
+
+It is also important to mention that for the configured clients of the auth providers, the authorization URLs are
+accessible by the `/oauth2/{provider}/auth` path where the `provider` variable represents the exact value of the auth
+provider backend `name` attribute.
+
+```python
+from fastapi_oauth2.client import OAuth2Client
+from fastapi_oauth2.config import OAuth2Config
+from social_core.backends.github import GithubOAuth2
+
+oauth2_config = OAuth2Config(
+    allow_http=False,
+    jwt_secret=os.getenv("JWT_SECRET"),
+    jwt_expires=os.getenv("JWT_EXPIRES"),
+    jwt_algorithm=os.getenv("JWT_ALGORITHM"),
+    clients=[
+        OAuth2Client(
+            backend=GithubOAuth2,
+            client_id=os.getenv("OAUTH2_CLIENT_ID"),
+            client_secret=os.getenv("OAUTH2_CLIENT_SECRET"),
+            redirect_uri="https://pysnippet.org/",
+            scope=["user:email"],
+        ),
+    ]
+)
+```
+
+## Integration
+
+To integrate the package into your FastAPI application, you need to add the `OAuth2Middleware` with particular configs
+in the above-represented format and include the router to the main router of the application.
+
+```python
+from fastapi import FastAPI
+from fastapi_oauth2.middleware import OAuth2Middleware
+from fastapi_oauth2.router import router as oauth2_router
+
+app = FastAPI()
+app.include_router(oauth2_router)
+app.add_middleware(OAuth2Middleware, config=oauth2_config)
+```
+
+After adding the middleware, the `user` attribute will be available in the request context. It will contain the user
+data provided by the OAuth2 provider.
+
+```jinja2
+{% if request.user.is_authenticated %}
+    <a href="/oauth2/logout">Sign out</a>
+{% else %}
+    <a href="/oauth2/github/auth">Sign in</a>
+{% endif %}
+```
+
+## Contribute
+
+Any contribution is welcome. If you have any ideas or suggestions, feel free to open an issue or a pull request. And
+don't forget to add tests for your changes.
