How to get started with strength training??

I'm a 25M working in IT and living with my family in a rural village. The closed gym for me is 30km so I can't go there. I started jogging 1 year back and incorporated yoga into my routine 2 months back. I want to improve my strength and I genuinely don't know how to get started??

I brought 5 x 2 dumbbells and am trying to workout by following Workout Guru videos on youtube and it's very confusing. I genuinely wanna improve my strength by working at my home, can someone tell me how to get started?? Any youtube channels to learn from??
