 # UBX GPS Library
+
+**This Arduino library was developed for the fastest and simplest communication with u-blox GPS modules**, which supports proprietary UBX protocol that is more compact than common NMEA. Main idea was to achieve real 10 Hz from NEO-7M and it was done.
+
+This library depends on device configuration and can handle only one type of UBX packet, which you can choose during [GPS device configuration](#gps-device-configuration). UBX GPS Library provides easy-to-use interface to all the available data in accordance with the Protocol Specification.
+
+## Quick Start
+
+Download `UbxGps` and place it to the Arduino libraries directory. Refer to [How to install Libraries](https://www.arduino.cc/en/Guide/Libraries) for details.
+
+Next step is configuring your GPS module properly, to find out how to do this see section [GPS device configuration](#gps-device-configuration).
+
+After that you can use included examples or play with following simple sketch:
+
+```cpp
+#include "UbxGpsNavPvt.h"
+
+UbxGpsNavPvt gps(Serial3);
+
+void setup() {
+    Serial.begin(9600);
+    gps.begin(9600);
+}
+
+void loop() {
+    if (gps.ready()) {
+        Serial.print(gps.lon / 10000000.0, 7); Serial.print(',');
+        Serial.print(gps.lat / 10000000.0, 7); Serial.print(',');
+        Serial.print(gps.height / 1000.0, 3); Serial.print(',');
+        Serial.println(gps.gSpeed * 0.0036, 5);
+    }
+}
+```
