+
+.SYNOPSIS
+Gets various information related to a running system's status for reporting.
+
+.DESCRIPTION
+Gathers the follow information from a provided list of computers. 
+The collected data is then returned as a DataTable or can be exported to a variety of file formats.
+Optional Metadata can be included to be included in the returned results/reports to assist in machine identification.
+
+Collected Data: Computer Name, Operating System, Operating System Build, Uptime, Recent Updates, Disk Space Utilization, Date Gathered
+Optional Metadata: Organization, Role, UpdateWindow
+
+.PARAMETER ComputerName
+Specifies a computer or set of computers that should be queried for their status.
+
+.PARAMETER CsvPath
+Path to a CSV that contains the list computers that should be collected.
+Optional metadata can be included that will be included in returned data.
+
+Columns: 
+Name*
+Organization
+Role
+UpdateWindow
+
+*: Required
+
+.PARAMETER Credential
+Credentials used for connecting to the specified computers to gather the machine's status information.
+
+.PARAMETER CredentialPath
+Path to stored credentials that will be imported using Import-Clixml to allow for storing credentials using a secure method.
+
+.PARAMETER OutputType
+Style of report that should be output. Defaults to JSON output but can be exported as a CSV or JSON.
+
+.PARAMETER OutputPath
+Path to where the report should be saved.
+
+.PARAMETER Organization
+Optional metadata that can be included in the returned results.
+
+.PARAMETER Role
+Optional metadata that can be included in the returned results.
+
+.PARAMETER UpdateWindow
+Optional metadata that can be included in the returned results.
