[Koha] Integrating RFID and KOHA

Dear Koha administrator, We are running Koha 3.16 in Debian 6.0.8 64 bits. Recently we installed RFID system in our Library and there it says that we need to have SIP2 in Koha in order to integrate with RFID and Koha. I have no knowledge on how to enable or install SIP2. It would be grate if you help me on this. Thank you Upendra
