Installation Guide issue

[pakistanimoon]

installation steps explain step 2 as download truffle dependencies using npm install but there is no package.json file exist inside blockchain folder how could npm install work there. to overcome this issue i first executed npm install @truffle/hdwallet-provider it sidplayed error of missing package that was Error: Cannot find module '@truffle/hdwallet-provider' to remove this error i executed npm install @truffle/hdwallet-provider then truffle compile it worked fine. or we need to add package.json file inside blockchain folder with code

{
  "dependencies": {
    "@truffle/hdwallet-provider": "^2.1.11"
  }
}
