-### SQL PowerShell Examples
-In order to use these examples (below), you need to install the SqlServer module from the [PowerShell Gallery](https://www.powershellgallery.com/packages/SqlServer).
-
-```powershell
-Install-Module -Name SqlServer -AllowPrerelease
-```
-
-In this example, we use the `Get-SqlInstance` cmdlet to Get the Server SMO objects for ServerA & ServerB.  The default output for this command will include the Instance name, version, Service Pack, & CU Update Level of the instances.
-
-```powershell
-Get-SqlInstance -ServerInstance ServerA, ServerB
-```
-
-Here is a sample of what that output will look like:
-
-```
-Instance Name             Version    ProductLevel UpdateLevel
--------------             -------    ------------ -----------
-ServerA                   13.0.5233  SP2          CU4
-ServerB                   14.0.3045  RTM          CU12
-```
-
-In this example, we will do a `dir` (alias for `Get-ChildItem`) to get the list of all SQL Server instances listed in your Registered Servers file, and then use the `Get-SqlDatabase` cmdlet to get a list of Databases for each of those instances.
-
-```powershell
-dir 'SQLSERVER:\SQLRegistration\Database Engine Server Group' -Recurse |
-WHERE { $_.Mode -ne 'd' } |
-FOREACH {
-    Get-SqlDatabase -ServerInstance $_.Name
-}
-```
-
-Here is a sample of what that output will look like:
-
-```
-Name                 Status           Size     Space  Recovery Compat. Owner
-                                            Available  Model     Level

-```
-
-This example uses the `Get-SqlDatabase` cmdlet to retrieve a list of all databases on the ServerB instance, then presents a grid/table (using the `Out-GridView` cmdlet) to select which databases should be backed up.  Once the user clicks on the "OK" button, only the highlighted databases will be backed up.
-
-```powershell
-Get-SqlDatabase -ServerInstance ServerB |
-Out-GridView -PassThru |
-Backup-SqlDatabase -CompressionOption On
-```
-
-This example, again, gets list of all SQL Server instances listed in your Registered Servers file, then calls the `Get-SqlAgentJobHistory` which reports every failed SQL Agent Job since Midnight, for each SQL Server instances listed.
-
-```powershell
-dir 'SQLSERVER:\SQLRegistration\Database Engine Server Group' -Recurse |
-WHERE {$_.Mode -ne 'd' } |
-FOREACH {
-    Get-SqlAgentJobHistory -ServerInstance  $_.Name -Since Midnight -OutcomesType Failed
-}
-```
