+!!! warning
+    This is a rather advanced topic.
+    
+    If you are starting with **FastAPI**, you might not need this.
+
+You can declare additional responses, with additional status codes, media types, descriptions, etc.
+
+Those additional responses will be included in the OpenAPI schema, so they will also appear in the API docs.
+
+But for those additional responses you have to make sure you return a `Response` like `JSONResponse` directly, with your status code and content.
+
+## Additional Response with `model`
+
+You can pass to your *path operation decorators* a parameter `responses`.
+
+It receives a `dict`, the keys are status codes for each response, like `200`, and the values are other `dict`s with the information for each of them.
+
+Each of those response `dict`s can have a key `model`, containing a Pydantic model, just like `response_model`.
+
+**FastAPI** will take that model, generate its JSON Schema and include it in the correct place in OpenAPI.
+
+For example, to declare another response with a status code `404` and a Pydantic model `Message`, you can write:
+
+
+```Python hl_lines="18 23"
+{!./src/additional_responses/tutorial001.py!}
+```
+
+!!! note
+    Have in mind that you have to return the `JSONResponse` directly.
+
+!!! info
+    The `model` key is not part of OpenAPI.
+
+    **FastAPI** will take the Pydantic model from there, generate the `JSON Schema`, and put it in the correct place.
+
+    The correct place is:
+    
+    * In the key `content`, that has as value another JSON object (`dict`) that contains:
+        * A key with the media type, e.g. `application/json`, that contains as value another JSON object, that contains:
+            * A key `schema`, that has as the value the JSON Schema from the model, here's the correct place.
+                * **FastAPI** adds a reference here to the global JSON Schemas in another place in your OpenAPI instead of including it directly. This way, other applications and clients can use those JSON Schemas directly, provide better code generation tools, etc.
+
+The generated responses in the OpenAPI for this *path operation* will be:
+
+```JSON hl_lines="3 4 5 6 7 8 9 10 11 12"
+{
+    "responses": {
+        "404": {
+            "description": "Additional Response",
+            "content": {

+                    "schema": {
+                        "$ref": "#/components/schemas/Message"
+                    }
+                }
+            }
+        },
+        "200": {
+            "description": "Successful Response",
+            "content": {
+                "application/json": {
+                    "schema": {
+                        "$ref": "#/components/schemas/Item"
+                    }
+                }
+            }
+        },

+            "content": {

+                }
+            }

+
+## Additional media types for the main response
+
+You can use this same `responses` parameter to add different media types for the same main response.
+
+For example, you can add an additional media type of `image/png`, declaring that your *path operation* can return a JSON object (with media type `application/json`) or a PNG image:
+
+```Python hl_lines="17 18 19 20 21 22 23 24 28"
+{!./src/additional_responses/tutorial002.py!}
+```
+
+!!! note
+    Notice that you have to return the image using a `FileResponse` directly.
+
+## Combining information
+
+You can also combine response information from multiple places, including the `response_model`, `status_code`, and `responses` parameters.
+
+You can declare a `response_model`, using the default status code `200` (or a custom one if you need), and then declare additional information for that same response in `responses`, directly in the OpenAPI schema.
+
+**FastAPI** will keep the additional information from `responses`, and combine it with the JSON Schema from your model.
+
+For example, you can declare a response with a status code `404` that uses a Pydantic model and has a custom `description`.
+
+And a response with a status code `200` that uses your `response_model`, but includes a custom `example`:
+
+```Python hl_lines="20 21 22 23 24 25 26 27 28 29 30 31"
+{!./src/additional_responses/tutorial003.py!}
+```
+
+It will all be combined and included in your OpenAPI, and shown in the API docs:
+
+<img src="/img/tutorial/additional-responses/image01.png">
+
+
+## Combine predefined responses and custom ones
+
+You might want to have some predefined responses that apply to many *path operations*, but you want to combine them with custom responses needed by each *path operation*.
+
+For those cases, you can use the Python technique of "unpacking" a `dict` with `**dict_to_unpack`:
+
+```Python
+old_dict = {
+    "old key": "old value",
+    "second old key": "second old value",
+}
+new_dict = {**old_dict, "new key": "new value"}
+```
+
+Here, `new_dict` will contain all the key-value pairs from `old_dict` plus the new key-value pair:
+
+```Python
+{
+    "old key": "old value",
+    "second old key": "second old value",
+    "new key": "new value",
+}
+```
+
+You can use that technique to re-use some predefined responses in your *path operations* and combine them with additional custom ones.
+
+For example:
+
+```Python hl_lines="11 12 13 14 15 24"
+{!./src/additional_responses/tutorial004.py!}
+```
+
+## More information about OpenAPI responses
+
+To see what exactly you can include in the responses, you can check these sections in the OpenAPI specification:
+
+* <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#responsesObject" target="_blank">OpenAPI Responses Object</a>, it includes the `Response Object`.
+* <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#responseObject" target="_blank">OpenAPI Response Object</a>, you can include anything from this directly in each response inside your `responses` parameter. Including `description`, `headers`, `content` (inside of this is that you declare different media types and JSON Schemas), and `links`.

+There are several things that you can configure in your FastAPI application.

-```Python

+* Description: the description of your API, in OpenAPI and the automatic API docs UIs.
+* Version: the version of your API, e.g. `v2` or `2.5.0`.

+You can also use <a href="https://github.com/encode/databases" target="_blank">`encode/databases`</a> with **FastAPI** to connect to databases using `async` and `await`.
+
+It is compatible with:
+
+* PostgreSQL
+* MySQL
+* SQLite
+
+In this example, we'll use **SQLite**, because it uses a single file and Python has integrated support. So, you can copy this example and run it as is.
+
+Later, for your production application, you might want to use a database server like **PostgreSQL**.
+
+!!! tip
+    You could adopt ideas from the previous section about <a href="/tutorial/sql-databases/" target="_blank">SQLAlchemy ORM</a>, like using utility functions to perform operations in the database, independent of your **FastAPI** code.
+
+    This section doesn't apply those ideas, to be equivalent to the counterpart in <a href="https://www.starlette.io/database/" target="_blank">Starlette</a>.
+
+## Import and set up `SQLAlchemy`
+
+* Import `SQLAlchemy`.
+* Create a `metadata` object.
+* Create a table `notes` using the `metadata` object.
+
+```Python hl_lines="4 14 16 17 18 19 20 21 22"

+    Notice that all this code is pure SQLAlchemy Core.
+
+    `databases` is not doing anything here yet.
+
+## Import and set up `databases`
+
+* Import `databases`.
+* Create a `DATABASE_URL`.
+* Create a `database` object.
+
+```Python hl_lines="3 9 12"
+{!./src/async_sql_databases/tutorial001.py!}
+```
+
+!!! tip
+    If you where connecting to a different database (e.g. PostgreSQL), you would need to change the `DATABASE_URL`.
+
+## Create the tables
+
+In this case, we are creating the tables in the same Python file, but in production, you would probably want to create them with Alembic, integrated with migrations, etc.
+
+Here, this section would run directly, right before starting your **FastAPI** application.
+
+* Create an `engine`.
+* Create all the tables from the `metadata` object.
+
+```Python hl_lines="25 26 27 28"
+{!./src/async_sql_databases/tutorial001.py!}
+```
+
+## Create models
+
+Create Pydantic models for:
+
+* Notes to be created (`NoteIn`).
+* Notes to be returned (`Note`).
+
+```Python hl_lines="31 32 33 36 37 38 39"
+{!./src/async_sql_databases/tutorial001.py!}
+```
+
+By creating these Pydantic models, the input data will be validated, serialized (converted), and annotated (documented).
+
+So, you will be able to see it all in the interactive API docs.
+
+## Connect and disconnect
+
+* Create your `FastAPI` application.
+* Create event handlers to connect and disconnect from the database.
+
+```Python hl_lines="42 45 46 47 50 51 52"
+{!./src/async_sql_databases/tutorial001.py!}
+```
+
+## Read notes
+
+Create the *path operation function* to read notes:
+
+```Python hl_lines="55 56 57 58"
+{!./src/async_sql_databases/tutorial001.py!}
+```
+
+!!! Note
+    Notice that as we communicate with the database using `await`, the *path operation function* is declared with `async`.
+
+### Notice the `response_model=List[Note]`
+
+It uses `typing.List`.
+
+That documents (and validates, serializes, filters) the output data, as a `list` of `Note`s.
+
+## Create notes

+
+### About `{**note.dict(), "id": last_record_id}`
+
+`note` is a Pydantic `Note` object.
+
+`note.dict()` returns a `dict` with its data, something like:
+
+```Python
+{
+    "text": "Some note",
+    "completed": False,
+}
+```
+
+but it doesn't have the `id` field.
+
+So we create a new `dict`, that contains the key-value pairs from `note.dict()` with:
+
+```Python
+{**note.dict()}
+```
+
+`**note.dict()` "unpacks" the key value pairs directly, so, `{**note.dict()}` would be, more or less, a copy of `note.dict()`.
+
+And then, we extend that copy `dict`, adding another key-value pair: `"id": last_record_id`:
+
+```Python
+{**note.dict(), "id": last_record_id}
+```
+
+So, the final result returned would be something like:
+
+```Python
+{
+    "id": 1,
+    "text": "Some note",
+    "completed": False,
+}
+```

+++ b/docs/tutorial/background-tasks.md
@@ -0,0 +1,96 @@
+You can define background tasks to be run *after* returning a response.
+
+This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving his response.
+
+This includes, for example:
+
+* Email notifications sent after performing an action:
+    * As connecting to an email server and sending an email tends to be "slow" (several seconds), you can return the response right away and send the email notification in the background.
+* Processing data:
+    * For example, let's say you receive a file that must go through a slow process, you can return a response of "Accepted" (HTTP 202) and process it in the background.
+
+## Using `BackgroundTasks`
+
+First, import `BackgroundTasks` and define a parameter in your *path operation function* with a type declaration of `BackgroundTasks`:
+
+```Python hl_lines="1 13"
+{!./src/background_tasks/tutorial001.py!}
+```
+
+**FastAPI** will create the object of type `BackgroundTasks` for you and pass it as that parameter.
+
+!!! tip
+    You declare a parameter of `BackgroundTasks` and use it in a very similar way as to when <a href="/tutorial/using-request-directly/" target="_blank">using the `Request` directly</a>.
+
+
+## Create a task function
+
+Create a function to be run as the background task.
+
+It is just a standard function that can receive parameters.
+
+It can be an `async def` or normal `def` function, **FastAPI** will know how to handle it correctly.
+
+In this case, the task function will write to a file (simulating sending an email). 
+
+And as the write operation doesn't use `async` and `await`, we define the function with normal `def`:
+
+```Python hl_lines="6 7 8 9"
+{!./src/background_tasks/tutorial001.py!}
+```
+
+## Add the background task
+
+Inside of your *path operation function*, pass your task function to the *background tasks* object with the method `.add_task()`:
+
+```Python hl_lines="14"
+{!./src/background_tasks/tutorial001.py!}
+```
+
+`.add_task()` receives as arguments:
+
+* A task function to be run in the background (`write_notification`).
+* Any sequence of arguments that should be passed to the task function in order (`email`).
+* Any keyword arguments that should be passed to the task function (`message="some notification"`).
+
+## Dependency Injection
+
+Using `BackgroundTasks` also works with the dependency injection system, you can declare a parameter of type `BackgroundTasks` at multiple levels: in a *path operation function*, in a dependency (dependable), in a sub-dependency, etc.
+
+**FastAPI** knows what to do in each case and how to re-use the same object, so that all the background tasks are merged together and are run in the background afterwards:
+
+```Python hl_lines="11 14 20 23"
+{!./src/background_tasks/tutorial002.py!}
+```
+
+In this example, the messages will be written to the `log.txt` file *after* the response is sent.
+
+If there was a query in the request, it will be written to the log in a background task.
+
+And then another background task generated at the *path operation function* will write a message using the `email` path parameter.
+
+## Technical Details
+
+The class `BackgroundTasks` comes directly from <a href="https://www.starlette.io/background/" target="_blank">`starlette.background`</a>.
+
+It is imported/included directly into FastAPI so that you can import it from `fastapi` and avoid accidentally importing the alternative `BackgroundTask` (without the `s` at the end) from `starlette.background`.
+
+By only using `BackgroundTasks` (and not `BackgroundTask`), it's then possible to use it as a *path operation function* parameter and have **FastAPI** handle the rest for you, just like when using the `Request` object directly.
+
+It's still possible to use `BackgroundTask` alone in FastAPI, but you have to create the object in your code and return a Starlette `Response` including it.
+
+You can see more details in <a href="https://www.starlette.io/background/" target="_blank">Starlette's official docs for Background Tasks</a>.
+
+## Caveat
+
+If you need to perform heavy background computation and you don't necessarily need it to be run by the same process (for example, you don't need to share memory, variables, etc), you might benefit from using other bigger tools like <a href="http://www.celeryproject.org/" target="_blank">Celery</a>.
+
+They tend to require more complex configurations, a message/job queue manager, like RabbitMQ or Redis, but they allow you to run background tasks in multiple processes, and especially, in multiple servers.
+
+To see an example, check the <a href="https://fastapi.tiangolo.com/project-generation/" target="_blank">Project Generators</a>, they all include Celery already configured.
+
+But if you need to access variables and objects from the same **FastAPI** app, or you need to perform small background tasks (like sending an email notification), you can simply just use `BackgroundTasks`.
+
+## Recap
+
+Import and use `BackgroundTasks` with parameters in *path operation functions* and dependencies to add background tasks.

+To add a function that should be run before the application starts, declare it with the event `"startup"`:
+
+```Python hl_lines="8"
+{!./src/events/tutorial001.py!}
+```
+
+In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.
+
+You can add more than one event handler function.
+
+And your application won't start receiving requests until all the `startup` event handlers have completed.
+
+## `shutdown` event
+
+To add a function that should be run when the application is shutting down, declare it with the event `"shutdown"`:
+
+```Python hl_lines="6"
+{!./src/events/tutorial002.py!}
+```
+
+Here, the `shutdown` event handler function will write a text line `"Application shutdown"` to a file `log.txt`.
+
+!!! info
+    In the `open()` function, the `mode="a"` means "append", so, the line will be added after whatever is on that file, without overwriting the previous contents.
+
+!!! tip
+    Notice that in this case we are using a standard Python `open()` function that interacts with a file.
+    
+    So, it involves I/O (input/output), that requires "waiting" for things to be written to disk.
+    
+    But `open()` doesn't use `async` and `await`.
+    
+    So, we declare the event handler function with standard `def` instead of `async def`.
+
+!!! info
+    You can read more about these event handlers in <a href="https://www.starlette.io/events/" target="_blank">Starlette's  Events' docs</a>.

+!!! warning
+    This is a rather advanced feature. You probably can skip it.
+
+    If you are just following the tutorial - user guide, you can probably skip this section.
+
+    If you already know that you need to modify the generated OpenAPI schema, continue reading.
+
+
+There are some cases where you might need to modify the generated OpenAPI schema.
+
+In this section you will see how.
+
+## The normal process
+
+The normal (default) process, is as follows.
+
+A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.
+
+As part of the application object creation, a *path operation* for `/openapi.json` (or for whatever you set your `openapi_url`) is registered.
+
+It just returns a JSON response with the result of the application's `.openapi()` method.
+
+By default, what the method `.openapi()` does is check the property `.openapi_schema` to see if it has contents and return them.
+
+If it doesn't, it generates them using the utility function at `fastapi.openapi.utils.get_openapi`.
+
+And that function `get_openapi()` receives as parameters:
+
+* `title`: The OpenAPI title, shown in the docs.
+* `version`: The version of your API, e.g. `2.5.0`.
+* `openapi_version`: The version of the OpenAPI specification used. By default, the latest: `3.0.2`.
+* `description`: The description of your API.
+* `routes`: A list of routes, these are each of the registered *path operations*. They are taken from `app.routes`.
+* `openapi_prefix`: The URL prefix to be used in your OpenAPI.
+
+## Overriding the defaults
+
+Using the information above, you can use the same utility function to generate the OpenAPI schema and override each part that you need.
+
+For example, let's add <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" target="_blank">ReDoc's OpenAPI extension to include a custom logo</a>.
+
+### Normal **FastAPI**
+
+First, write all your **FastAPI** application as normally:
+
+```Python hl_lines="1 4 7 8 9"
+{!./src/extending_openapi/tutorial001.py!}
+```
+
+### Generate the OpenAPI schema
+
+Then, use the same utility function to generate the OpenAPI schema, inside a `custom_openapi()` function:
+
+```Python hl_lines="2 15 16 17 18 19 20"
+{!./src/extending_openapi/tutorial001.py!}
+```
+
+### Modify the OpenAPI schema
+
+Now you can add the ReDoc extension, adding a custom `x-logo` to the `info` "object" in the OpenAPI schema:
+
+```Python hl_lines="21 22 23"
+{!./src/extending_openapi/tutorial001.py!}
+```
+
+### Cache the OpenAPI schema
+
+You can use the property `.openapi_schema` as a "cache", to store your generated schema.
+
+That way, your application won't have to generate the schema every time a user opens your API docs.
+
+It will be generated only once, and then the same cached schema will be used for the next requests.
+
+```Python hl_lines="13 14 24 25"
+{!./src/extending_openapi/tutorial001.py!}
+```
+
+### Override the method
+
+Now you can replace the `.openapi()` method with your new function.
+
+```Python hl_lines="28"
+{!./src/extending_openapi/tutorial001.py!}
+```

+
+Once you go to <a href="http://127.0.0.1:8000/redoc" target="_blank">http://127.0.0.1:8000/redoc</a> you will see that you are using your custom logo (in this example, **FastAPI**'s logo):

+
+You can declare a response to be the `Union` of two types, that means, that the response would be any of the two.
+
+It will be defined in OpenAPI with `anyOf`.
+
+To do that, use the standard Python type hint <a href="https://docs.python.org/3/library/typing.html#typing.Union" target="_blank">`typing.Union`</a>:

+## Duplicate headers
+
+It is possible to receive duplicate headers. That means, the same header with multiple values.
+
+You can define those cases using a list in the type declaration.
+
+You will receive all the values from the duplicate header as a Python `list`.
+
+For example, to declare a header of `X-Token` that can appear more than once, you can write:
+
+```Python hl_lines="9"
