# Installing Metamask & Adding Polygon Network

### Install the MetaMask Extension <a href="#install-the-metamask-extension" id="install-the-metamask-extension"></a>

First, you'll start with a fresh and default [MetaMask](https://metamask.io/) installation from the Chrome store. After downloading, installing, and initializing the extension, follow the **Get Started** guide. In there, you need to create a wallet, set a password, and store your secret backup phrase (this gives direct access to your funds, so make sure to store these in a secure place).

### Create a Wallet <a href="#create-a-wallet" id="create-a-wallet"></a>

After installing [MetaMask](https://metamask.io/), the setup will automatically open a new task with a welcome screen. Click **Get Started** to begin the setup process.

When prompted, you are given the option to import a wallet using a recovery seed phrase. For this exercise, set up a new wallet.
