storage space error with Arduino Nano

[Amir-SSDC]

Hi,
i'm using Arduino Nano as advised in the readme file, however when i try to upload the code it gives me the below error.

text section exceeds available space in boardSketch uses 31066 bytes (101%) of program storage space. Maximum is 30720 bytes.

Global variables use 1062 bytes (51%) of dynamic memory, leaving 986 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it.
Error compiling for board Arduino Nano.

Are you using Arduino Nano or something else?
