+### Locks and Function Invocations
+
+The `withoutOverlapping` method provides a simple syntax for executing a given closure while holding an atomic lock, allowing you to ensure only one instance of the closure is running at a given time across your entire infrastructure:
+
+```php
+Cache::withoutOverlapping('foo', function () {
+    // Lock acquired after waiting a maximum of 10 seconds...
+});
+```
+
+By default, the lock will not be released until the closure finishes executing, and the method will wait up to 10 seconds to acquire the lock. You may customize these values by passing additional arguments to the method:
+
+```php
+Cache::withoutOverlapping('foo', function () {
+    // Lock acquired for 120 seconds after waiting a maximum of 5 seconds...
+}, lockSeconds: 120, waitSeconds: 5);
+```
+
+If the lock cannot be acquired within the specified wait time, an `Illuminate\Contracts\Cache\LockTimeoutException` will be thrown.
