# Get Started

### Prerequisites

Before you begin, ensure you have the following installed:

* Node.js (version 18 or higher)
* npm / yarn / pnpm
* Git (for cloning the repository)

1. **Install SDK**
   * install the required npm packages:
   * ```bash
     npm install satoshi-sdk
     ```
2. **import package**
   * In your TypeScript or JavaScript project, import the SDK:
   * ```javascript
     import { SatoshiClient } from 'satoshi-sdk';
     ```

### Example: Calculate Minting Fee

This example shows how to use the Satoshi Protocol SDK to calculate the minting fee for a given amount of satUSD using a specific collateral type on the `BEVM_MAINNET`. It utilizes several functions and configurations provided by the SDK to accomplish this.

#### Code

```typescript
import { getPublicClientByConfig, ProtocolConfigMap } from 'satoshi-sdk';

// Define the protocol configuration for the BEVM_MAINNET
const protocolConfig = ProtocolConfigMap.BEVM_MAINNET;

// Select the first collateral type available in the configuration
const collateral = protocolConfig.COLLATERALS[0];

// Get a public client configured for the selected protocol configuration
const publicClient = getPublicClientByConfig(protocolConfig);

// Define the amount for which the minting fee needs to be calculated
const amount = 123456789n;  // Using a BigInt for large numbers

// Async function to perform the minting fee calculation
async function calculateMintingFee() {
  const result = await getBorrowingFee(
    {
      publicClient,
      protocolConfig,
      troveManagerAddr: collateral.TROVE_MANAGER_BEACON_PROXY_ADDRESS,
    },
    amount
  );
  
  // Log the result to the console
  console.log('Minting Fee:', result);
}

// Call the function to execute the operation
calculateMintingFee();
```
