+### Including the log category in text-format sink output
+All _Microsoft.Extensions.Logging.ILogger_ implementations are created with a specified [_log category_](https://learn.microsoft.com/en-us/dotnet/core/extensions/logging?tabs=command-line#log-category) string, which is then attached as structured data to each log message created by that `ILogger` instance. Typically, the log category is the fully-qualified name of the class generating the log messages. This convention is implemented by the [`ILogger<TCategoryName>`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.logging.ilogger-1) interface, which is commonly used as an injected dependency in frameworks that use _Microsoft.Extensions.Logging_.
+
+_Serilog.Extensions.Logging_ captures the `ILogger`'s log category, but it's not included in the default output templates for text-based sinks, such as [Console](https://github.com/serilog/serilog-sinks-console), [File](https://github.com/serilog/serilog-sinks-file) and [Debug](https://github.com/serilog/serilog-sinks-debug).
+
+To include the log category in the final written messages, add the `{SourceContext}` named hole to a customised `outputTemplate` parameter value when configuring the relevant sink(s). For example:
+```csharp
+.WriteTo.Console(
+    outputTemplate: "[{Timestamp:HH:mm:ss} {Level:u3}] {SourceContext}: {Message:lj}{NewLine}{Exception}")
+.WriteTo.File("log.txt",
+    outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {SourceContext}: {Message:lj}{NewLine}{Exception}")
+```

 Using the extension method will add a `Scope` property to your log events. This is most useful for adding simple "scope strings" to your events, as in the following code:
 
 ```csharp
-using (_logger.BeginScope("Transaction")) {

 If you simply want to add a "bag" of additional properties to your log events, however, this extension method approach can be overly verbose. For example, to add `TransactionId` and `ResponseJson` properties to your log events, you would have to do something like the following:

 A far better alternative is to use the `BeginScope<TState>(TState state)` method. If you provide any `IEnumerable<KeyValuePair<string, object>>` to this method, then Serilog will output the key/value pairs as structured properties _without_ the `Scope` property, as in this example:
