+You can, *in theory* and *on average*, construct 643,000 messages per second.
 
 I don't know how to benchmark a logger without logging messages to stdout,<br>
 so I created a dedicated `bench` function on each source that just *constructs* them.
 
-Deferred is not really much faster, but can be helpful in some scenarios. I think. Maybe.

+You might prefer to defer logs in asynchronous situations where order does not matter and<br>
+you'd like to prevent slowing down I/O.<br>
+You might also prefer to reset all sources to synchronous logging during app shutdown.<br>
+This can help debug issues with how your app closes. (see example below)
+
+## Global resets
+Every source is tracked by this module in a `Set`.
+
+You can reset every source's log timing or time format with `LoggingConfiguration.reset(something)`.<br>
+The corresponding property will be updated on `LoggingConfiguration`:
+
+```ts
+import Logging, { LoggingConfiguration, LogTiming } from "@proxnet/undead-logging";
+
+const log = new Logging("Logger");
+
+log.logTiming = LogTiming.Sync; // the default
+LoggingConfiguration.resetLogTiming = LogTiming.Deferred;
+
+// both are LogTiming.Deferred
+log.d(`My log timing: LogTiming.${LogTiming[log.logTiming]}`);
+log.d(`Global: LogTiming.${LogTiming[LoggingConfiguration.logTiming]}`);
+```
+
+This is useful when you want to use synchronous logging during a shutdown:
+```ts
+// something is keeping the event loop alive (HTTP server, a database, some I/O?)
+
+LoggingConfiguration.logTiming = LogTiming.Deferred;
+const log = new Logging("Main");
+
+Deno.addSignalListener('SIGINT', () => {
+    LoggingConfiguration.resetLogTiming = LogTiming.Sync;
+});
+```
