+.SYNOPSIS
+    The script validates if the Splunk OpenTelemetry .NET Deployer TA can be
+    installed and uninstalled successfully by Splunk.
+
+.DESCRIPTION
+    The script extracts the Splunk OpenTelemetry .NET Deployer TA from a .tgz file
+    and installs it. It then validates the installation by checking if the expected
+    files and directories are present. The script also uninstalls the Splunk OpenTelemetry
+    .NET instrumentation, by changing the local configuration of the Deployer TA
+    and validates the uninstallation by once again checking if the instrumentation
+    files and folders were removed.
+
+.PARAMETER tgzFilePath
+    Path to the .tgz file containing the Splunk OpenTelemetry .NET Deployer TA.
+
+.PARAMETER splunkInstallPath
+    Path to the Splunk installation directory.
+
+.PARAMETER splunkAppName
+    Actual name on the disk of the folder with the Splunk OpenTelemetry .NET
+    Deployer TA app.
