title: React + redux project not launching with instructions
body: <p>This is my first React + Redux project, it works when I run it in my PC but when people follow my github instructions to run the project on their computers they get an error. "command not found: yarn"</p>
  
  <p>Can anyone help me with this issue please? I wonder if my instructions are wrong in the first place
