+# http-parser
+
+Small http message parsing library. Keep in mind that this library only handles
+parsing the http request into a method, headers and body.
+
+## Basic usage
+
+```c
+
+static void onRequest(struct http_parser_event *ev) {
+  // The request has been received
+  // Answer the request directly or pass it to a route handler of sorts
+}
+
+// Initialize a request
+struct http_parser_request *request = http_parser_init();
+
+// Assign userdata into the request
+// Use it to track whatever you need
+request->udata = (void*)...;
+
+// Attach a function
+
+// Stored http message
+char *message =
+  "GET / HTTP/1.1\r\n"
+  "Host: localhost\r\n"
+  "\r\n"
+;
+
+// Passing network data into it
+http_parser_request_data(request, message, strlen(message));
+```
