I build this for my colg project

1. root folder( ./)

   npm i
   

   let it finish

2. go to client (./bill_ocr)

   cd bill_ocr/
   npm i

   let it finish

3. go to ocr-server folder

   cd ocr-server/
   npm i
   

4. last step (at root folder)

   ```bash
   npm run dev
   ```
   

   NOTE: if u want to run both backend and frontend separate then skip step 4 (for more information visit package.json file)

   npm run server

   open another terminal

   npm run client
