# Installing and Setting up Metamask

### Step 1 - Install Metamask

Download the [Metamask](https://metamask.io/) wallet browser extension or mobile app.

If you're new, click **Create a Wallet**. If you already have a compatible wallet, you can also select **Import Wallet**.

Your wallet information is extremely important and very sensitive. If you lose your seed phrase, no one can recover it for you which means that your account, along with your tokens and items, will be lost forever. Please take the time to create a strong password and to securely store your recovery information.

### Step 2 - Add Polygon to Metamask

In Metamask, click on the current network which is Ethereum Mainnet by default. At the bottom of the list of networks, click **Add Network**.

* **Network Name:** `Polygon Mainnet`
* **RPC URL:** `https://polygon-rpc.com`
* **Chain ID:** `137`
* **Symbol:** `MATIC`
* **Block explorer:** `https://polygonscan.com`

After filling in all the details, click **Save**. You will now find the newly added Polygon Mainnet in the network list.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://whitepaper.mintofdestiny.xyz/techy-stuff/installing-and-setting-up-metamask.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
