Work flow

1. Use the truffle unbox pet-shop as the template
2. Write the contract in the remix ide
3. Once, it is successfully runned, write this code inside the /Contracts folder (.sol as extension).
4. Inside the /Migrations folder, write the migration code (.js as extension)

truffle compile truffle migrate --reset With this the bc part would be over

4. Inside the /src folder, edit the index.html and js/app.js folder, to create the front end
5. Open the ganache network and connect it with metamask
6. Run the npm run dev cmd to run the project
