 ## How to use
-You will need to glue ``int (*write_and_read)(unsigned char *data, size_t sz)``
+You will probably need to include the header and source file to your
+project and glue ``int (*write_and_read)(unsigned char *data, size_t sz)``
 and ``void (*chip_enable)(unsigned val)`` functions to your specific SPI 
-hardware. See examples folders on how to initialze and configure structs.
+HAL vendor calls.
