2. Rename the .env.example in the healtcare-client folder to .env

The short way (using scripts)

3. Start the services:

   Step 1: In the root folder, run:

   sh run_1.sh

   Step 2: Open a new terminal and run:

   sh run_2.sh

   Step 3: Open another terminal and run:

   sh run_3.sh

The Long way

3.1. Install the dependencies using

pnpm i

in folder healthcare-client, oracle, and smart-Contract

3.2. Run

npx hardhat node

in the smart-contract folder to deploy the chain

3.3. Start a new terminal and run

sh deploy_contract.sh

in the smart-contract folder to deploy the contract

3.3. Run the frontend with

pnpm run dev

In the healthcare-client

3.4. Run the oracle with

pnpm run dev

In the oracle folder

After doing all the initial setup (using the script or the long way) 4. You need to import a wallet in metamask extension in browser with private key:
