I am a newbie to this channel and to building my new magic mirror, I have purchased a raspberry pie 4 and the rest of my materials and am about to embark on my build.

I wanted to know if anyone could help/direct me in where I could find ways to help me show how I can use Netflix and control my Raspberry pie through say my phone once I have built everything and have the mirror hanging on the wall.

Any help would be great. Thanks
