+### Jobs.find
+
+`Jobs.find` allows you to find a single pending job by its arguments, and run logic against it. You can pass in a callback in the end to check for the document, and you can run the same operations with-in the function scope as you would with `Jobs.register`, as well as `this.run` as a shortcut to `Jobs.run`.
+
+```javascript
+Jobs.find("sendReminder", "[email protected]", "The future is here!", function (jobDoc) {
+	if (jobDoc)  {
+		this.reschedule({
+			in: {
+				minutes: 5
+			}
+		});
+
+		return jobDoc;
+	} else {
+		this.run({
+			in: {
+				minutes: 5
+			}
+		})
+	}
+});
+```
+
 ### Jobs.execute
 
 `Jobs.execute` allows you to run a job ahead of its due date. It can only work on jobs that have not been resolved.
