-Alright, you made it here. The tough part is done.
+After Home Assistant has been [installed](/installation/) on your device, there are 5 steps to complete setting up Home Assistant.
 
-- As the last step of the [installation procedure](/installation/) specific to your device, you entered the Home Assistant device's address in your browser's address bar.
-    - Typically, this is `http://homeassistant.local:8123/`.
-    - If you are running an older Windows version or have a stricter network configuration, you might need to access Home Assistant at <a href="http://homeassistant:8123" target="_blank">homeassistant:8123</a> or `http://X.X.X.X:8123` (replace X.X.X.X with your device's IP address).
-
-    - **Result**: You now see the welcome screen. Depending on your hardware, preparation may take a while.
+1. Enter the following URL into the browser's address bar: [http://homeassistant.local:8123/](http://homeassistant.local:8123/).
+   - **Result**: You now see the **Preparing Home Assistant** page. Depending on your hardware and internet connection, preparation may take a while.
+     - Home Assistant downloads the latest version of {% term "Home Assistant Core" %} (about 700&nbsp;MB).
+   - If you ran into issues with this step, refer to the [installation troubleshooting](/installation/troubleshooting/).
+   - Once preparation is finished, the welcome screen is shown.

-    - Depending on the preinstalled software version, you might see a slightly different version of the welcome screen.
-      - To view the log files, select the pulsing blue dot.

-With Home Assistant installed, it's time to set up the basics.
-
-We will now create the owner's account of Home Assistant. This account is an administrator account. It will always be able to change everything.
- 
-1. If you want to restore from a backup of a previous installation, select **Restore from backup**.
-    - Continue with the procedure on [restoring from backup](/common-tasks/os/#restoring-a-backup).
-    - Ignore the rest of this procedure. The following steps describe how to create a new installation, not how to restore from backup.
-2. If this is your initial installation, select **Create my smart home**.
-3. Enter a name, username, and password.
-   - Make sure the username is lowercase and doesn't contain white space.
-   - Store the name, username, and password in a password manager. There is no way to recover the owner credentials.
-   - Select **Create account**.
+2. You can either create a new installation or recover an existing installation from a backup:
+   - **Option 1: new installation**: If this is your initial installation, we will now create the owner's account of Home Assistant.
+     - {% icon "mdi:information-outline" %} This account is an administrator account. It will always be able to change everything.
+     - Select **Create my smart home**.
+     - Enter a name, username, and password.
+       - Make sure the username is lowercase and contains no whitespace.
+     - Store the name, username, and password somewhere safe. There is no way to recover the owner credentials.
+     - Select **Create account**.

-4. Enter the location of your home.
-   - The location is used to populate settings such as time zone, unit system, and currency.
-   - It is also used for location-based information and automations: for example showing the weather-forecast, opening the shades at sunrise, or starting the vacuum when you leave the home.
-   - If you'd rather not send your location, you can choose a location far away from where you live.
+   - **Option 2: restore from backup**: If you want to restore a backup of a previous installation, select **Restore from backup**.
+     - Ignore the rest of this procedure and continue with the procedure on [restoring from backup](/common-tasks/os/#restoring-a-backup).
+
+3. Enter the location of your home.
+   - The location is used to configure the time zone, unit system, and currency.
+   - It is also used for automations such as showing the weather, opening the shades at sunrise, or starting the vacuum when you leave the home.
    - You can always change this information later in the settings.
+   - After finding your location, select **Next**.
