Good Ways to Increase your Imaan?

:salam:

Brothers and Sisters,

As all of you know Ramadhan is the greatest month in Islam. So in this month the chief Shaytaans are locked up and it is the best month to get closer to Allah :taala: and his Deen. So does anyone have anything that will help increase one's Imaan? Any sunnah prayers or anything? If you Sunnah prayers can you explain to me how to pray them?

:jazak:

Ramadhan Mubarak :-)
