First, You Need to Install a Wallet. Below is a guide to installing Metamask.
Click “Get Chrome Extension” to install Metamask.
Click “Add to Chrome” in the upper right.
Click “Add Extension” to complete the installation. You will know Metamask has been installed when you see the fox logo on the upper right hand corner of your browser.
One of the first tasks you will want to do on Metamask is to install a wallet to hold your cryptocurrencies. To do this, follow the instructions below.
Step 1. Click on the Metamask logo in the upper right hand corner of your Google Chrome browser.
Step 2. Read and agree to the terms and conditions. You may have to agree with 2 to 3 pages worth of terms.
Step 3. Enter a password and click “Create” to create your wallet.
Step 4. You will see a set of 12 “seed words” for your vault. Click “Save Seed Words as File” and copy the “MetaMask Seed Words” file that is downloaded to a safe place. You will need it to access your wallet on another device, if something ever happens to the device you are currently downloading Metamask on.
Your Metamask wallet is now ready!
