Different instructions depending where you look, yarn install vs npm install

Can someone help me determine if we need to use Yarn install or NPM install? depending where I look, both can be found as the proper next step, but they do download many different things.

Iโ€™m not sure by different things, but what you need to know is they both do the same thing, to install dependencies.

So itโ€™s mostly a preference to use either npm install or yarn install

Thank you. I was able to get past this, but I do appreciate the help. Seems like yarn install is the better route per some more recent things Iโ€™ve seen. I ended up refreshing my laptop and things started working for me. I kept getting errors, must have been something I didnโ€™t have set up right on my systems. Drove me crazy for awhile there. Too much work to refresh that right now. Itโ€™s nice being mobile anyways. Thanks again!
