[GUIDE] Echo Speaks Server on Docker (or without)

Good morning Sir. Can you help me? I am following your instructions on installing echo speak without docker.
Ok made some progress but stuck. I installed node and npm. I confirmed by doing a node - v and npm -v in a cmd prompt. I also tested my server with hello word.

But where/how do I type the following command (remember I am on Windows!)

Install and Run the Server:

Log in with the user who will run the server (does not need to be root).
Change to directory you wish to run the server from (can be home folder, subfolders will be created).

sudo npm install -g pm2
npm i https://github.com/tonesto7/echo-speaks-server
cd node_modules/echo-speaks-server
pm2 -n echo-speaks start index.js
pm2 startup
pm2 save
pm2 list

Thank you!
