 ## Deploy Smart Contract via Remix
 
-Remix is great as it is a zero-setup tool for working with smart contracts, allowing us to easily demonstrate the Chainlink oracle contracts. But first - let’s inspect the contracts we’ll be working with!

 ## FeedConsumer
 
-This is the contract you will deploy. This is just a minimal example to demonstrate how to consume Chainlink data feeds on Zilliqa. You can extend this to be a decentralised borrowing and lending protocol, a DEX, game, NFT minting contract - anything you can think of!

 If you look at the last function, it only returns the current answer, or price. You can see that it also is capable of returning other pieces of information such as timestamp data. Chainlink encourages dAapp developers to verify the timestamp together with the price information to protect against stale data. While the oracles should be publishing fresh data every other minute, there can be unexpected downtime.

 The next thing to do is to compile our contracts with the built-in compiler. Do this for both contracts:

 Let’s call the description function: after a couple of seconds you should see “ZIL / USD”. Do the same with decimals and getLatestAnswer() and you should see a similar result as below:

 Remember since this is on-chain data, there are no floats / decimal numbers. So to get the nominal value in a more human readable format, you divide the answer with the decimal points as follows:
 
 `1791000 / 1e8 = 0.01791 USD for 1 ZIL.`
 
-There you have it! While this a simple demonstration, it should illuminate the wide range of possibilities that can be materialised on Zilliqa now that Chainlink oracles are active on the network.
