-## Arduino Memory usage
-Out of the box, this library has been setup to use a 'medium' amount of memory (read below how to reduce the memory footprint). Extended callbacks are not enabled by default, and can be anabled by `#USE_EXT_CALLBACKS`. See the callback examples.
-
-This library is **not using any dynamic memory** allocation methods - all buffers have a fixed size, set in the `AppleMIDI_Settings.h` file, avoiding potential memory leaks and memory fragmentation (also, no usage of the String() class).
-
-The minimum buffer size (`MaxBufferSize`) should be set to 64 bytes (also the default). Setting it to a higher value will make sending larger SysEx messages more efficiant (large SysEx messages are chopped in pieces, the larger the buffer, the less pieces needed), at the price of a bigger memory footprint.
-
-`MaxNumberOfParticipants` is another way to cut memory - each session particpant uses approx 300 bytes. Default number of participants is 2 (each using 2 sockets). 
-Beware: the number of sockets on the Arduino is limited. The W5100 support 4 (hance default number of participants is 2), the W5200 and W5500 based IP chips can use 8 sockets. (Base port can be set in `APPLEMIDI_CREATE_DEFAULT_INSTANCE`)
-
-Reduce the memory footprint by a further wopping 500 bytes by `#define NO_SESSION_NAME` before `#include <AppleMIDI.h>`. This will leave out all the code to manage the optional session name. The RtpMIDI service client will show the name as (manually) defined in the directory.
-
-Even further reduce the memory footprint by `#define ONE_PARTICIPANT` limiting the number of particpants to just 1.
-On an UNO the absolute minimum memory footprint is 21966 bytes (68%) and 945 global variables (46%). For a Leonardo that is 24906 bytes (86%) and 1111 bytes  (43%) of global variables.

 ## Notes
 
 ### Session names
 
 Session names can get really long on Macs (eg 'Macbook Pro of Johann Gambolputty .. von Hautkopft of Ulm') and will be trunctated to the `MaxSessionNameLen` (as set in the settings file).
 
+### memory footprint
+The memory footprint of the library can be lowered significantly, read the [wiki](https://github.com/lathoub/Arduino-AppleMIDI-Library/wiki/Memory-footprint)

 ### Ethernet buffer size
 It's highly recommended to modify the [Ethernet library](https://github.com/arduino-libraries/Ethernet) or use the [Ethernet3 library](https://github.com/sstaub/Ethernet3) to avoid buffer overruns - [learn more](https://github.com/lathoub/Arduino-AppleMIDI-Library/wiki/Enlarge-Ethernet-buffer-size-to-avoid-dropping-UDP-packages)
