Hi.
I have fallen in love with the piano due to my obsession of watching piano covers on my favourite songs. This has motivated and inspired me to learn the piano. But after searching various websites I am worrying a little bit. Everyone says I must use a full sized weighted keyboard atleast and start getting piano lessons from professionals. But I cannot afford this because of my financial status, the maximum investment I can make is books (and even that might be hard

). However, I have a Yamaha keyboard sitting in the cupboard with a stand -- that's all I have.
So I gave up on searching because of all the same answers I'm getting. So I'm asking you people what is the best way to learn piano without piano lessons. Like any book recommendations, websites, videos, etc? My aim is to be able to be able understand all the theory involved: chords, scales, etc. And be able to read sheet music so I can play my favourite songs.
Thank you for your help and hopefully you all will be able to help me persue my dream!
