-SYNOPSIS
-    Adds or removes databases to the specified availability group.
-
-PARAMETER DatabaseName
-    The name of the database(s) to add to the availability group. This accepts wildcards.
-
-PARAMETER ServerName
-    Hostname of the SQL Server where the primary replica of the availability group lives. If the
-    availability group is not currently on this server, the resource will attempt to connect to the
-    server where the primary replica lives.
-
-PARAMETER InstanceName
-    Name of the SQL instance where the primary replica of the availability group lives. If the
-    availability group is not currently on this instance, the resource will attempt to connect to
-    the instance where the primary replica lives.
-
-PARAMETER AvailabilityGroupName
-    The name of the availability group in which to manage the database membership(s).
-
-PARAMETER BackupPath
-    The path used to seed the availability group replicas. This should be a path that is accessible
-    by all of the replicas.
-
-PARAMETER Ensure
-    Specifies the membership of the database(s) in the availability group. The options are:
-
-        - Present:  The defined database(s) are added to the availability group. All other
-                    databases that may be a member of the availability group are ignored.
-        - Absent:   The defined database(s) are removed from the availability group. All other
-                    databases that may be a member of the availability group are ignored.
-
-    The default is 'Present'.
-
-PARAMETER Force
-    When used with "Ensure = 'Present'" it ensures the specified database(s) are the only databases
-    that are a member of the specified Availability Group.
-
-    This parameter is ignored when 'Ensure' is 'Absent'.
-
-PARAMETER MatchDatabaseOwner
-    If set to $true, this ensures the database owner of the database on the primary replica is the
-    owner of the database on all secondary replicas. This requires the database owner is available
-    as a login on all replicas and that the PsDscRunAsCredential has impersonate any login, control
-    server, impersonate login, or control login permissions.
-
-    If set to $false, the owner of the database will be the PsDscRunAsCredential.
-
-    The default is '$false'.
-
-.PARAMETER ProcessOnlyOnActiveNode
-    Specifies that the resource will only determine if a change is needed if the target node is the active host of the SQL Server Instance.
-
-.PARAMETER StatementTimeout
-    Set the query StatementTimeout in seconds. Default 600 seconds (10mins).
