 ## DESCRIPTION
+This cmdlet creates a new theme or updates an existing theme. The color pairs settings can be passed as a hash table, while the color palette settings can be passed as either a hash table or a dictionary.
+
+Adding a theme does not automatically apply it to any site. Instead, the theme becomes available in the list of themes under the **Change the look** option for modern SharePoint pages.
+
+Choose the appropriate parameter set based on whether you're working with a legacy or modern theme format. For details about the new theme format, see [Site theme](/sharepoint/site-theme).
+
+> [!NOTE]
+> In multi-geo environments, themes added by an administrator in the primary geography are automatically propagated and available across the organization. This cmdlet is not supported for administrators in satellite geographies.
 
-The **Add-SPOTheme** cmdlet creates a new theme or updates an existing theme. The color palette settings can be passed as either a hash table or a dictionary.
+## Examples
 
-Adding a theme does not apply the theme to any sites. It adds the theme to your tenant store, and then the theme is available in the list of themes under the **Change the look** option for modern pages.

+  )
+}
+
+Add-SPOTheme -Identity "Teal Theme" -ColorPairs $colorPairs
+```
+
+This example creates a theme named `"Teal Theme"` with color pair settings in various shades of teal.
+
+### Example 2:
+
+```powershell
+Add-SPOTheme -Identity "Teal Theme" -ColorPairs $colorPairs -Overwrite
+```
 
-### Example 1
+To update an existing theme in the new format, modify the color settings using the same syntax as when creating a theme. Add the `-Overwrite` flag to the Add-SPOTheme cmdlet.
 
-In this example, a new theme named `"Custom Cyan"` is created, with color palette settings that are various shades of cyan. Note that the settings are passed as a hash table.
+### Example 3:

 > [!NOTE]
 > Prior to the December 2017 release of the SPO Management Shell, the **Add-SPOTheme** cmdlet required that color palette settings be passed as a dictionary. We recommend that you use the latest version of the SPO Management Shell, or use the `HashToDictionary` function to convert a hash table to a dictionary if needed.
 
-### Example 2
-
-If you want to update an existing theme (to modify some of its color settings, for example), use the same syntax as shown previously, but add the `-Overwrite` flag to the **Add-SPOTheme** cmdlet.
+### Example 4: Overwrite a legacy format theme 
 
 ```powershell
 Add-SPOTheme -Identity "Custom Cyan" -Palette $themepalette -IsInverted $false -Overwrite
 ```
 
+To update an existing legacy format theme and modify its color settings, use the same syntax as when creating the theme. Add the `-Overwrite` flag to the Add-SPOTheme cmdlet.
