 The blog post [ESPFlash: An Arduino Library for Storing Data in the ESP Filesystem](https://dalegi.com/2020/04/22/espflash-an-arduino-library-for-storing-data-in-the-esp-filesystem/) contains some useful comparisons between ESPFlash usage and SPIFFS usage. In addition, here are some basic ESPFlash example:
 - Simple ESPFlash integer example - Create ESPFlash instance with file name of "exampleInteger". Set a single elements value, and get it back.
 ```c++
+SPIFFS.begin()
 ESPFlash<int> espFlashInteger("/exampleInteger");
 espFlashInteger.set(10);
 int testInteger = espFlashInteger.get();
 ```
 - Simple ESPFlash vector example - Create ESPFlash instance with file name of "exampleInteger". Append 10 randomly generated elements. Get the elements back.
 
 ```c++
+SPIFFS.begin()
 ESPFlash<int> espFlashInteger("/exampleArray");
 for(int ii = 0; ii < 10; ii++)
