# Mint Position (add liquidity)

This is an example of creating a new position in Pangea's pool or depositing additional liquidity in an existing position.

```typescript
import { ethers } from "ethers";
import {BigNumber} from "@ethersproject/bignumber";

/// concentrated Liquidity Pool Manager address
const poolManagerAddress = "0x000...";

/// web3 Provider (metamask provider / jsonRPC provider / ...)
const provider = ethers.getDefaultProvider();

// Create new position
async function createPosition(
    poolAddress:string,
    lowerTick:number,
    upperTick:number,
    amount0Desired:BigNumber,
    amount1Desired:BigNumber
) {
      const pool = await ConcentratedLiquidityPool__factory.connect(poolAddress, provider);
      const token0 = await ERC20__factory.connect(await pool.token0(), provider);
      const token1 = await ERC20__factory.connect(await pool.token1(), provider);        
            
      const poolManager = await ConcentratedLiquidityPoolManager__factory.connect(positionManagerAddress, provider);
      // first, approve      
      await (await token0.approve(poolManager.address,amount0Desired)).wait();
      await (await token1.approve(poolManager.address, amount1Desired)).wait();
      
      // second, mint postion
      const tx = await poolManager.mint(
            poolAddress, 
            0, // if the lowerOld is not set, will search and input automatically
            lowerTick,
            0, // if the upperOld is not set, will search and input automatically
            uppterTick,
            amount0Desired,
            amount1Desired,
            0,
            0 // if positionId = 0 create new. else, add liquidity to the positionId
      );
      await tx.wait();
}
```
