I set up a create-react-app and I'm trying to run App.js on localhost, but upon doing yarn start I get the following error message:

22:23 $ yarn start

yarn run v1.3.2

$ react-scripts start

Could not find a required file.

  Name: index.html

  Searched in: /Users/-----/Desktop/---/----/hw/HW-REPO/hw-name/public

error Command failed with exit code 1.

I'd already installed yarn with yarn install, so I'm not sure if there's something wrong with my code or with the file structure.

Here's the file structure:

app-name

 -client

   --public

     ---index.html

     ---manifest.json

   --src

     ---Components

        ----various folders

     ---App.js

     ---App.test.js

     ---index.js

 -database

 -model

 -gitignore

 -package-lock.json

 -package.json

 -server.js

 -yarn.lock
