Your account address: 0x586497e77b4631CE9C6fE7B5E261A6A7364B0087

This simple Turorial will guide you on how to setup and test an Celo account.

This is from the Celo Document guide : https://docs.celo.org/developer-guide/start/hellocelo

1:
Get the repository from : git clone https://github.com/critesjosh/helloCelo.git
2:
install the dependencies with 
npm i 
3:
Here you learn how to first get an account Celo account, Get credit from the Celo Faucet to do a Transaction
1 
use the script helloCello.js
you should fill each sequence with the code providing here

// 1. Import web3 and contractkit 
const Web3 = require("web3")
const ContractKit = require('@celo/contractkit')

// 2. Init a new kit, connected to the alfajores testnet
const web3 = new Web3('https://alfajores-forno.celo-testnet.org')
const kit = ContractKit.newKitFromWeb3(web3)

At that point you can test console.log and kit you should have an Object

// 3. Get the token contract wrappers
let goldtoken = await kit.contracts.getGoldToken()
let stabletoken = await kit.contracts.getStableToken()

// 4. Address to look up
let anAddress = '0xD86518b29BB52a5DAC5991eACf09481CE4B0710d'

Here you will learn how to query an account , you will query the account above for test 

// 5. Get token balances
let celoBalance = await goldtoken.balanceOf(anAddress)
let cUSDBalance = await stabletoken.balanceOf(anAddress)

// Print balances
console.log(`${anAddress} CELO balance: ${celoBalance.toString()}`)
console.log(`${anAddress} cUSD balance: ${cUSDBalance.toString()}`)

Now using getAccount.js you will create a new Celo account;
no need to change getAccount.js it is imported and called in helloCelo.js

//
// Create an Account
//

// 6. Import the getAccount function
const getAccount = require('./getAccount').getAccount

async function createAccount(){
    // 7. Get your account
    let account = await getAccount()

    // 8. Get the token contract wrappers
    let goldtoken = await kit.contracts.getGoldToken()
    let stabletoken = await kit.contracts.getStableToken()

    // 9. Get your token balances
    let celoBalance = await goldtoken.balanceOf(account.address)
    let cUSDBalance = await stabletoken.balanceOf(account.address)

    // Print your account info
    console.log(`Your account address: ${account.address}`)
    console.log(`Your account CELO balance: ${celoBalance.toString()}`)
    console.log(`Your account cUSD balance: ${cUSDBalance.toString()}`)
}

Now you have a new account in my case it is 
Your account address: 0x586497e77b4631CE9C6fE7B5E261A6A7364B0087
Your account CELO balance: 0
Your account cUSD balance: 0

You should use the Celo Faucet Test to test the transaction: https://celo.org/developers/faucet
You only to paste you address in the faucet and you get some credti for test network

run helloCelo and you should get

Your account address: 0x586497e77b4631CE9C6fE7B5E261A6A7364B0087
Your account CELO balance: 5000000000000000000
Your account cUSD balance: 10000000000000000000

now to do a transaction 
async function send(){
    // 10. Get your account
    let account = await getAccount()

    // 11. Add your account to ContractKit to sign transactions
    kit.connection.addAccount(account.privateKey)

    // 12. Specify recipient Address
    let anAddress = '0xD86518b29BB52a5DAC5991eACf09481CE4B0710d'

    // 13. Specify an amount to send
    let amount = 100000

    // 14. Get the token contract wrappers    
    let goldtoken = await kit.contracts.getGoldToken()
    let stabletoken = await kit.contracts.getStableToken()

    // 15. Transfer CELO and cUSD from your account to anAddress
    // Specify cUSD as the feeCurrency when sending cUSD
    let celotx = await goldtoken.transfer(anAddress, amount).send({from: account.address})
    let cUSDtx = await stabletoken.transfer(anAddress, amount).send({from: account.address, feeCurrency: stabletoken.address})

    // 16. Wait for the transactions to be processed
    let celoReceipt = await celotx.waitReceipt()
    let cUSDReceipt = await cUSDtx.waitReceipt()

    // 17. Print receipts
    console.log('CELO Transaction receipt: %o', celoReceipt)
    console.log('cUSD Transaction receipt: %o', cUSDReceipt)

    // 18. Get your new balances
    let celoBalance = await goldtoken.balanceOf(account.address)
    let cUSDBalance = await stabletoken.balanceOf(account.address)

    // 19. Print new balance
    console.log(`Your new account CELO balance: ${celoBalance.toString()}`)
    console.log(`Your new account cUSD balance: ${cUSDBalance.toString()}`)
}

you should have this output
