+## API
+
+### llhttp_settings_t
+
+The settings object contains a list of callbacks that the parser will invoke.
+
+The following callbacks can return `0` (proceed normally), `-1` (error) or `HPE_PAUSED` (pause the parser):
+
+* `on_message_begin`: Invoked when a new request/response starts.
+* `on_message_complete`: Invoked when a request/response has been completedly parsed.
+* `on_url_complete`: Invoked after the URL has been parsed.
+* `on_method_complete`: Invoked after the HTTP method has been parsed.
+* `on_version_complete`: Invoked after the HTTP version has been parsed.
+* `on_status_complete`: Invoked after the status code has been parsed.
+* `on_header_field_complete`: Invoked after a header name has been parsed.
+* `on_header_value_complete`: Invoked after a header value has been parsed.
+* `on_chunk_header`: Invoked after a new chunk is started. The current chunk length is stored in `parser->content_length`.
+* `on_chunk_extension_name_complete`: Invoked after a chunk extension name is started.
+* `on_chunk_extension_value_complete`: Invoked after a chunk extension value is started.
+* `on_chunk_complete`: Invoked after a new chunk is received. 
+* `on_reset`: Invoked after `on_message_complete` and before `on_message_begin` when a new message 
+   is received on the same parser. This is not invoked for the first message of the parser.
+
+The following callbacks can return `0` (proceed normally), `-1` (error) or `HPE_USER` (error from the callback): 
+
+* `on_url`: Invoked when another character of the URL is received. 
+* `on_status`: Invoked when another character of the status is received.
+* `on_method`: Invoked when another character of the method is received. 
+   When parser is created with `HTTP_BOTH` and the input is a response, this also invoked for the sequence `HTTP/`
+   of the first message.
+* `on_version`: Invoked when another character of the version is received.
+* `on_header_field`: Invoked when another character of a header name is received.
+* `on_header_value`: Invoked when another character of a header value is received.
+* `on_chunk_extension_name`: Invoked when another character of a chunk extension name is received.
+* `on_chunk_extension_value`: Invoked when another character of a extension value is received.
+
+The callback `on_headers_complete`, invoked when headers are completed, can return:
+
+* `0`: Proceed normally.
+* `1`: Assume that request/response has no body, and proceed to parsing the next message.
+* `2`: Assume absence of body (as above) and make `llhttp_execute()` return `HPE_PAUSED_UPGRADE`.
+* `-1`: Error
+* `HPE_PAUSED`: Pause the parser.
+
+### `void llhttp_init(llhttp_t* parser, llhttp_type_t type, const llhttp_settings_t* settings)`
+
+Initialize the parser with specific type and user settings.
+
+### `uint8_t llhttp_get_type(llhttp_t* parser)`
+
+Returns the type of the parser.
+
+### `uint8_t llhttp_get_http_major(llhttp_t* parser)`
+
+Returns the major version of the HTTP protocol of the current request/response.
+
+### `uint8_t llhttp_get_http_minor(llhttp_t* parser)`
+
+Returns the minor version of the HTTP protocol of the current request/response.
+
+### `uint8_t llhttp_get_method(llhttp_t* parser)`
+
+Returns the method of the current request.
+
+### `int llhttp_get_status_code(llhttp_t* parser)`
+
+Returns the method of the current response.
+
+### `uint8_t llhttp_get_upgrade(llhttp_t* parser)`
+
+Returns `1` if request includes the `Connection: upgrade` header.
+
+### `void llhttp_reset(llhttp_t* parser)`
+
+Reset an already initialized parser back to the start state, preserving the 
+existing parser type, callback settings, user data, and lenient flags.
+
+### `void llhttp_settings_init(llhttp_settings_t* settings)`
+
+Initialize the settings object.
+
+### `llhttp_errno_t llhttp_execute(llhttp_t* parser, const char* data, size_t len)`
+
+Parse full or partial request/response, invoking user callbacks along the way.
+
+If any of `llhttp_data_cb` returns errno not equal to `HPE_OK` - the parsing interrupts, 
+and such errno is returned from `llhttp_execute()`. If `HPE_PAUSED` was used as a errno, 
+the execution can be resumed with `llhttp_resume()` call.
+
+In a special case of CONNECT/Upgrade request/response `HPE_PAUSED_UPGRADE` is returned 
+after fully parsing the request/response. If the user wishes to continue parsing, 
+they need to invoke `llhttp_resume_after_upgrade()`.
+
+**if this function ever returns a non-pause type error, it will continue to return 
+the same error upon each successive call up until `llhttp_init()` is called.**
+
+### `llhttp_errno_t llhttp_finish(llhttp_t* parser)`
+
+This method should be called when the other side has no further bytes to
+send (e.g. shutdown of readable side of the TCP connection.)
+
+Requests without `Content-Length` and other messages might require treating
+all incoming bytes as the part of the body, up to the last byte of the
+connection. 
+
+This method will invoke `on_message_complete()` callback if the
+request was terminated safely. Otherwise a error code would be returned.
+
+
+### `int llhttp_message_needs_eof(const llhttp_t* parser)`
+
+Returns `1` if the incoming message is parsed until the last byte, and has to be completed by calling `llhttp_finish()` on EOF.
+
+### `int llhttp_should_keep_alive(const llhttp_t* parser)`
+
+Returns `1` if there might be any other messages following the last that was
+successfully parsed.
+
+### `void llhttp_pause(llhttp_t* parser)`
+
+Make further calls of `llhttp_execute()` return `HPE_PAUSED` and set
+appropriate error reason.
+
+**Do not call this from user callbacks! User callbacks must return
+`HPE_PAUSED` if pausing is required.**
+
+### `void llhttp_resume(llhttp_t* parser)`
+
+Might be called to resume the execution after the pause in user's callback.
+
+See `llhttp_execute()` above for details.
+
+**Call this only if `llhttp_execute()` returns `HPE_PAUSED`.**
+
+### `void llhttp_resume_after_upgrade(llhttp_t* parser)`
+
+Might be called to resume the execution after the pause in user's callback.
+See `llhttp_execute()` above for details.
+
+**Call this only if `llhttp_execute()` returns `HPE_PAUSED_UPGRADE`**
+
+### `llhttp_errno_t llhttp_get_errno(const llhttp_t* parser)`
+
+Returns the latest error.
+
+### `const char* llhttp_get_error_reason(const llhttp_t* parser)`
+
+Returns the verbal explanation of the latest returned error.
+
+**User callback should set error reason when returning the error. See
+`llhttp_set_error_reason()` for details.**
+
+### `void llhttp_set_error_reason(llhttp_t* parser, const char* reason)`
+
+Assign verbal description to the returned error. Must be called in user
+callbacks right before returning the errno.
+
+**`HPE_USER` error code might be useful in user callbacks.**
+
+### `const char* llhttp_get_error_pos(const llhttp_t* parser)`
+
+Returns the pointer to the last parsed byte before the returned error. The
+pointer is relative to the `data` argument of `llhttp_execute()`.
+
+**This method might be useful for counting the number of parsed bytes.**
+
+### `const char* llhttp_errno_name(llhttp_errno_t err)`
+
+Returns textual name of error code.
+
+### `const char* llhttp_method_name(llhttp_method_t method)`
+
+Returns textual name of HTTP method.
+
+### `const char* llhttp_status_name(llhttp_status_t status)`
+
+Returns textual name of HTTP status.
+
+### `void llhttp_set_lenient_headers(llhttp_t* parser, int enabled)`
+
+Enables/disables lenient header value parsing (disabled by default).
+Lenient parsing disables header value token checks, extending llhttp's
+protocol support to highly non-compliant clients/server. 
+
+No `HPE_INVALID_HEADER_TOKEN` will be raised for incorrect header values when
+lenient parsing is "on".
+
+**USE AT YOUR OWN RISK!**
+
+### `void llhttp_set_lenient_chunked_length(llhttp_t* parser, int enabled)`
+
+Enables/disables lenient handling of conflicting `Transfer-Encoding` and
+`Content-Length` headers (disabled by default).
+
+Normally `llhttp` would error when `Transfer-Encoding` is present in
+conjunction with `Content-Length`. 
+
+This error is important to prevent HTTP request smuggling, but may be less desirable
+for small number of cases involving legacy servers.
+
+**USE AT YOUR OWN RISK!**
+
+### `void llhttp_set_lenient_keep_alive(llhttp_t* parser, int enabled)`
+
+Enables/disables lenient handling of `Connection: close` and HTTP/1.0
+requests responses.
+
+Normally `llhttp` would error on (in strict mode) or discard (in loose mode)
+the HTTP request/response after the request/response with `Connection: close`
+and `Content-Length`. 
+
+This is important to prevent cache poisoning attacks,
+but might interact badly with outdated and insecure clients. 
+
+With this flag the extra request/response will be parsed normally.
+
+**USE AT YOUR OWN RISK!**
+
+### `void llhttp_set_lenient_transfer_encoding(llhttp_t* parser, int enabled)`
+
+Enables/disables lenient handling of `Transfer-Encoding` header.
+
+Normally `llhttp` would error when a `Transfer-Encoding` has `chunked` value
+and another value after it (either in a single header or in multiple
+headers whose value are internally joined using `, `).
+
+This is mandated by the spec to reliably determine request body size and thus
+avoid request smuggling.
+
+With this flag the extra value will be parsed normally.
+
+**USE AT YOUR OWN RISK!**
