 If you are using the Dead Reckoning Sensor Fusion or High Dynamic Rate messages, you will need to make more small changes to your code. Please see the [dead reckoning examples](./examples/Dead_Reckoning) for more details. There is more detail available in [Theory.md](./Theory.md#migrating-your-code-to-v20) if you need it.
 
+## Memory Usage
+
+The u-blox GNSS library has grown considerably over the years and v2.0.8 came very close to completely filling the program memory on platforms like the ATmega328 (Arduino Uno).
+If you want to reduce the amount of memory used by the library, you can edit the header file (_SparkFun_u-blox_GNSS_Arduino_Library.h_) and uncomment line 60:
+
+```
+#define SFE_UBLOX_REDUCED_PROG_MEM // Uncommenting this line will delete the minor debug messages to save memory
+```
+
+Doing this will save approximately 15% of program memory on the ATmega328.
+
+On Windows platforms, you will normally find _SparkFun_u-blox_GNSS_Arduino_Library.h_ in:
+- Documents\Arduino\libraries\SparkFun_u-blox_GNSS_Arduino_Library\src

 ## SPI Support
 
 In v2.0.8 we added support for SPI, based on a contribution by @aberridg. Thank you Andrew!
