# Upkeep Subscriptions

### Introduction

Upkeeps are contracts you set up on Chainlink Automation that allow anyone to run a smart contract function automatically according to a custom predefined schedule. Time-based upkeeps are similar to cron jobs. Upkeeps are a part of the [Chainlink Automation Product](https://docs.chain.link/chainlink-automation).

### Usage

To start using this module, initialize the Dev3 SDK & Chainlink KeeperRegsitry instances first, like this:

```typescript
import { Dev3SDK, KeeperRegistry } from "dev3-sdk";

var dev3: Dev3SDK;
var keeperRegistry: KeeperRegistry;

async function init() {
    dev3 = new Dev3SDK("<your api key>", "<your project id>");
    keeperRegistry = new KeeperRegistry();
    return keeperRegistry.init();
}

init();
```

Once initialization function is finished, you can start using the Upkeep Subscriptions module by interacting with the functions registry object!
