# Installing MetaMask

{% hint style="success" %}
This guide is primarily intended for first time MetaMask and Lattice users, but you might find it useful even if you're not new to the app and you want to make sure you're doing everything right when installing a MetaMask instance on a new computer or re-installing.
{% endhint %}

1\. Download and install **the extension** - make sure to get the browser one!

{% embed url="<https://metamask.io/download/>" %}

2\. **Pin the extension in your browser** so you can access it with a single click:

3\. Open the extension and then click on **Create a new wallet\*.**

{% hint style="success" %}
**\*Why create a wallet and not import your existing one?**

This is because MetaMask has to have a default hot wallet (Account 1), which cannot be a hardware wallet. You've already imported your wallet to the Lattice1 (or created a new one) during the initial device setup and now you just need to **establish a connection** between your hardware wallet and MetaMask - we'll get there soon!

If you want to use the Lattice along with hot wallets, you should instead select **I have an existing wallet** and import your hot wallet seed phrase on the next step.

Remember that you do NOT need to import your Lattice seed phrase into MetaMask to set this up.
{% endhint %}

4\. On the next step, select **Use Secret Recovery Phrase** and then create your **MetaMask password**. This password is only used to access the browser extension - if you forget it, you can re-install the extension and set a new one. **Check the box** and click on **Create password**.

5. Then, you can confirm the hot wallet seed phrase, but if you do not intend to use the hot wallet on MetaMask, you can just skip this step by clicking on **Remind me later**. Then, select what kind of user data you want the app to collect and on the next step, click on **Done**.

You should now see the MetaMask homescreen and you can now move on to **connecting your Lattice hardware wallet to the extension**. See the next article to find out how to do that.
