-Wrapping with another logger
-----------------------------
+### Wrapping with another logger
 
-Users that might want to wrap this logger to be able to catch log events for various 
-reasons can setup the logger as follows:
+You might want to wrap this logger to do your own processing before handing events to a SimpleLogger instance. Instead
+of calling `init()` which calls `log::set_max_level` and `log::set_boxed_logger`, you can call those functions directly
+giving you the chance to wrap or adjust the logger. See [wrap.rs](examples/wrap.rs) for a more detailed example.
 
-On windows machines:
-```rust
-let logger = SimpleLogger::new();
-set_up_color_terminal();
-let max_level = logger.max_level(); 
-```
+The call to `set_up_color_terminal()` is currently only needed on Windows when the `colored` feature is enabled. If
+you're not on Windows and not using the `colored` feature, it will do nothing. 
 
-Otherwise:
 ```rust
-let logger = SimpleLogger::new();
-let max_level = logger.max_level();
-```
+use simple_logger::{SimpleLogger, set_up_color_terminal};
 
-The user can then themselves call `log::set_max_level` and `log::set_boxed_logger` or equivalent as they wish.
+fn main() {
+    set_up_color_terminal();
+
+    let logger = SimpleLogger::new();
+    let max_level = logger.max_level();
+
+    log::set_max_level(max_level);
+    log::set_boxed_logger(Box::new(logger)).unwrap();
+}
+```
