+For more information, check the [Serilog.Settings.Configuration](https://github.com/serilog/serilog-settings-configuration) documentation.
+
+For example, to add logging to a file, you should add the following snippet to your configuration:
+
+```json
+"Serilog": {
+  "Using": [
+    "Serilog.Sinks.File"
+  ],
+  "WriteTo": [
+    {
+      "Name": "File",
+      "Args": {
+        "path": "logs/log.txt",
+        "rollingInterval": "Day"
+      }
+    }
+  ]
+}
+```
+
+Next to that, you also need to copy over Serilog.Sinks.File.dll from [NuGet](https://www.nuget.org/packages/Serilog.Sinks.File/). See the [Serilog.Sinks.File documentation](https://github.com/serilog/serilog-sinks-file#json-appsettingsjson-configuration) for a list of parameters that can be configured.
+
+Other Serilog sinks are also supported, but are out of scope for this documentation.
