-# IniFile example
-
-## Instructions for use
-
-  * Copy the `net.ini` file to the root directory of your (micro)SD card.
-  * Modify the `IniFileExample.ino` file so that `SD_SELECT` defines
-  the correct pin number.
-  * Compile and upload the sketch. 
-
-
-## Expected output
-
-It may take a few seconds from the sketch starting before anything is
-printed to the serial port, be patient. If the sketch runs correctly
-the output should appear as below:
-
-
-    Ini file exists
-    section 'network' has an entry 'mac' with value 01:23:45:67:89:AB
-    Could not read 'nosuchkey' from section 'network', error was key not found
-    Could not read 'nosuchkey' from section 'nosuchsection', error was section not found
-    The value of 'allow put' in section '/upload' is TRUE
-
-
-If the SD card is missing or cannot be read the sketch will print:
-
-    SD.begin() failed
-
