+### View application logs using Powershell
+
+This command saves you having to use Windows Event Viewer. It gets the 5 most recent logs from the `Application` log, for the source (application) named `Alloy`:
+
+```
+Get-EventLog -LogName Application -Source Alloy -Newest 5 | format-table -wrap
+```
+
+Gives a readable, wrapped output like this:
+
+```
+PS C:\Users\azureuser> Get-EventLog -LogName Application -Source Alloy -Newest 5 | format-table -wrap
+
+   Index Time          EntryType   Source                 InstanceID Message
