enable us to do that:

<h4>1. Metamask chrome extension</h4>
<div>
You can install the{' '}
<a href={constants.URL_METAMASK_CHROME_STORE} target="_blank">
Metamask
</a>{' '}
Chrome extension Ethereum wallet. Once installed and set up, refresh this page.
<div className="pt1">
<span className="bold">Note:</span> If you already have Metamask installed, make sure it is
unlocked.
</div>
</div>
<h4>Parity Signer</h4>
<div>
The{' '}
<a href={constants.URL_PARITY_CHROME_STORE} target="_blank">
Parity Signer Chrome extension
</a>{' '}
lets you connect to a locally running Parity node. Make sure you have started your local Parity node
with {configs.IS_MAINNET_ENABLED && '`parity ui` or'} `parity --chain kovan ui` in order to connect
to {configs.IS_MAINNET_ENABLED ? 'mainnet or Kovan respectively.' : 'Kovan.'}
</div>
<div className="pt2">
<span className="bold">Note:</span> If you have done one of the above steps and are still seeing
this message, we might still be unable to retrieve an Ethereum address by calling
`web3.eth.accounts`. Make sure you have created at least one Ethereum address.

{configs.IS_MAINNET_ENABLED
? ` or ${constants.MAINNET_NAME} (network Id: ${constants.NETWORK_ID_MAINNET}).`

If you are using{' '}
