The following section is a copy of what is received in an introductory email from Amazon after purchasing an Echo Input.
Download the Alexa App
Once you receive your new Echo Input, download the Alexa App in your mobile browser at https://alexa.amazon.co.uk or in your mobile app store (Android and iOS).
Opening the app will immediately start the setup process.
During setup, you'll connect Echo Input to the Internet, so you'll need your Wi-Fi password.
Once you've connected to Wi-Fi and associated Echo Input with your Amazon account, you're ready to start using your device.
Now you can use the Alexa App to manage your contacts, view your to-do and shopping lists, remotely control music on your Echo Input, link your accounts, access the Settings menu and much more.
