WordPress Advice, Need Help!

Hey Everyone,

I would like to begin creating wordpress themes from scratch and was wondering where I should start learning the necessary coding involved to do so. Does anyone have any advice as to where I can start? Or any resources that will help me get started?

From my understanding I must use HTML, CSS and finally convert it to PHP in order to create a functioning wordpress theme?

I have been working with pre-made themes for almost a year now and would like to increase my knowledge by creating themes myself.

If anyone has any advice on where I can get started it would be greatly appreciated!

Thanks!
