+Async dispatch is supported.

+from jsonrpcserver import async_dispatch, async_method, Ok, Result
+
+@async_method
+async def ping() -> Result:
+    return Ok("pong")
+
+await async_dispatch('{"jsonrpc": "2.0", "method": "ping", "id": 1}')
+```
+
+Some reasons to use this:
+
+- Use it with an asynchronous protocol like sockets or message queues.
+- `await` long-running functions from your method.
+- Batch requests are dispatched concurrently.
+
+## Notifications
+
+Notifications are requests without an `id`. We should not respond to
+notifications, so jsonrpcserver gives an empty string to signify there is *no
+response*.
+
+```python
+>>> await async_dispatch('{"jsonrpc": "2.0", "method": "ping"}')
+''
+```
+
+If the response is an empty string, don't send it.
+
+```python
+if response := dispatch(request):
+    send(response)
+```
+
+```{note}
+A synchronous protocol like HTTP requires a response no matter what, so we can
+send back the empty string. However with async protocols, we have the choice of
+responding or not.

+# Dispatch
+
+The `dispatch` function processes a JSON-RPC request, attempting to call the method(s)
+and gives a JSON-RPC response.
+
+```python
+>>> dispatch('{"jsonrpc": "2.0", "method": "ping", "id": 1}')
+'{"jsonrpc": "2.0", "result": "pong", "id": 1}'
+```
+
+It's a pure function; it will always give you a JSON-RPC response. No exceptions will be
+raised.
+
+[See how dispatch is used in different frameworks.](examples)
+
+## Optional parameters
+
+The `dispatch` function takes a request as its argument, and also has some optional
+parameters that allow you to customise how it works.
+
+### methods
+
+This lets you specify the methods to dispatch to. It's an alternative to using
+the `@method` decorator. The value should be a dict mapping function names to
+functions.
+
+```python
+def ping():
+    return Ok("pong")
+
+dispatch(request, methods={"ping": ping})
+```
+
+Default is `global_methods`, which is an internal dict populated by the
+`@method` decorator.
+
+### context
+
+If specified, this will be the first argument to all methods.
+
+```python
+@method
+def greet(context, name):
+    return Ok(f"Hello {context}")
+
+>>> dispatch('{"jsonrpc": "2.0", "method": "greet", "params": ["Beau"], "id": 1}', context="Beau")
+'{"jsonrpc": "2.0", "result": "Hello Beau", "id": 1}'
+```
+
+### deserializer
+
+A function that parses the JSON request string. Default is `json.loads`.
+
+```python
+dispatch(request, deserializer=ujson.loads)
+```
+
+### jsonrpc_validator
+
+A function that validates the request once the JSON string has been parsed. The
+function should raise an exception (any exception) if the request doesn't match
+the JSON-RPC spec (https://www.jsonrpc.org/specification). Default is
+`default_jsonrpc_validator` which uses Jsonschema to validate requests against
+a schema.
+
+To disable JSON-RPC validation, pass `jsonrpc_validator=lambda _: None`, which
+will improve performance because this validation takes around half the dispatch
+time.
+
+### args_validator
+
+A function that validates a request's parameters against the signature of the
+Python function that will be called for it. Note this should not validate the
+_values_ of the parameters, it should simply ensure the parameters match the
+Python function's signature. For reference, see the `validate_args` function in
+`dispatcher.py`, which is the default `args_validator`.
+
+### serializer
+
+A function that serializes the response string. Default is `json.dumps`.
+
+```python
+dispatch(request, serializer=ujson.dumps)
+```

+## How to disable schema validation?
+
+Validating requests is costly - roughly 40% of dispatching time is spent on schema validation.
+If you know the incoming requests are valid, you can disable the validation for better
+performance.
+
+```python
+dispatch(request, validator=lambda _: None)
+```
+
+## Which HTTP status code to respond with?
+
+I suggest:
+
+```python
+200 if response else 204
+```
+
+If the request was a notification, `dispatch` will give you an empty string. So
+since there's no http body, use status code 204 - no content.
+
+## How to rename a method
+
+Use `@method(name="new_name")`.
+
+Or use the dispatch function's [methods
+parameter](https://www.jsonrpcserver.com/en/latest/dispatch.html#methods).
+
+## How to get the response in other forms?
+
+Instead of `dispatch`, use:
+
+- `dispatch_to_serializable` to get the response as a dict.
+- `dispatch_to_response` to get the response as a namedtuple (either a
+  `SuccessResponse` or `ErrorResponse`, these are defined in
+  [response.py](https://github.com/explodinglabs/jsonrpcserver/blob/main/jsonrpcserver/response.py)).
+
+For these functions, if the request was a batch, you'll get a list of
+responses. If the request was a notification, you'll get `None`.

+# Jsonrpcserver
+
+Jsonrpcserver processes JSON-RPC requests.
+
+## Quickstart
+
+Install jsonrpcserver:
+```python
+pip install jsonrpcserver
+```
+
+Create a `server.py`:
+
+```python
+from jsonrpcserver import method, serve, Ok
+
+@method
+def ping():
+    return Ok("pong")
+
+if __name__ == "__main__":
+    serve()
+```
+
+Start the server:
+```sh
+$ python server.py
+```
+
+Send a request:
+```sh
+$ curl -X POST http://localhost:5000 -d '{"jsonrpc": "2.0", "method": "ping", "id": 1}'
+{"jsonrpc": "2.0", "result": "pong", "id": 1}
+```
+
+`serve` starts a basic development server. Do not use it in a production deployment. Use
+a production WSGI server instead, with jsonrpcserver's [dispatch](dispatch) function.

+# Methods
+
+Methods are functions that can be called by a JSON-RPC request.
+
+## Writing methods
+
+To write a method, decorate a function with `@method`:
+
+```python
+from jsonrpcserver import method, Error, Ok, Result
+
+@method
+def ping() -> Result:
+    return Ok("pong")
+```
+
+If you don't need to respond with any value simply `return Ok()`.
+
+## Responses
+
+Methods return either `Ok` or `Error`. These are the [JSON-RPC response
+objects](https://www.jsonrpc.org/specification#response_object) (excluding the
+`jsonrpc` and `id` parts). `Error` takes a code, message, and optionally
+'data'.
+
+```python
+@method
+def test() -> Result:
+    return Error(1, "There was a problem")
+```
+
+Alternatively, raise a `JsonRpcError`, which takes the same arguments as `Error`.
+
+## Parameters
+
+Methods can accept arguments.
+
+```python
+@method
+def hello(name: str) -> Result:
+    return Ok("Hello " + name)
+```
+
+Testing it:
+
+```sh
+$ curl -X POST http://localhost:5000 -d '{"jsonrpc": "2.0", "method": "hello", "params": ["Beau"], "id": 1}'
+{"jsonrpc": "2.0", "result": "Hello Beau", "id": 1}
+```
+
+## Invalid params
+
+A common error response is *invalid params*.
+The JSON-RPC error code for this is **-32602**. A shortcut, *InvalidParams*, is
+included so you don't need to remember that.
+
+```python
+from jsonrpcserver import dispatch, method, InvalidParams, Ok, Result
+
+@method
+def within_range(num: int) -> Result:
+    if num not in range(1, 5):
+        return InvalidParams("Value must be 1-5")
+    return Ok()
+```
+
+This is the same as saying
+```python
+return Error(-32602, "Invalid params", "Value must be 1-5")
+```
