+    Detects broken or otherwise damaged Group Policies providing insight whether GPO exists in both AD and SYSVOL.
+    It provides few statuses:
+    - Permissions issue - means account couldn't read GPO due to permissions
+    - ObjectClass issue - means that ObjectClass is of type Container, rather than expected groupPolicyContainer
+    - Not available on SYSVOL - means SYSVOL data is missing, yet AD metadata is available
+    - Not available in AD - means AD metadata is missing, yet SYSVOL data is available
+    - Exists - means AD metadata and SYSVOL data are available

+    Finds and removes broken Group Policies from SYSVOL or AD or both. Assesment is based on Get-GPOZaurrBroken and there are 3 supported types:
+    - AD - meaning GPOs which have no SYSVOL content will be deleted from AD
+    - SYSVOL - meaning GPOs which have no AD content will be deleted from SYSVOL
+    - ObjectClass - meaning GPOs which have ObjectClass category of Container rather than groupPolicyContainer will be deleted from AD & SYSVOL
+
+    .PARAMETER Type
+    Choose one or more types to delete. Options are AD, ObjectClass, SYSVOL
+
+    .PARAMETER BackupPath
+    Path to optional backup of SYSVOL content before deletion
+
+    .PARAMETER BackupDated
+    Forces backup to be created within folder that has date in it
+
+    .PARAMETER LimitProcessing
+    Allows to specify maximum number of items that will be fixed in a single run. It doesn't affect amount of GPOs processed
+
+    .PARAMETER Forest
+    Target different Forest, by default current forest is used
+
+    .PARAMETER ExcludeDomains
+    Exclude domain from search, by default whole forest is scanned
+
+    .PARAMETER IncludeDomains
+    Include only specific domains, by default whole forest is scanned
