MFRC522 Tips and Trics

Dear All,

I am a freelancer and working on MFRC522 for quite some time.
One thing I wondered was the quality of documents and information around MFRC522 available online.
I was planning to invest some time and prepare certain documentation to bring all information in one document or maybe a few documents.
I am eager to know from you all what and all I can include in the same.

Few things I am planning to add are below
1).Antenna Design Guide.
2).UART And I2C Communication Firmware with MFRC522
3). Schematic Diagram for the MFRC522 as per available boards in market

Thanks And Regards,
Dixit Patel
