 _Please note that the Pagination class is still in the works. Only one bug is currently known, and it's that the Pagination will error when a user tries to end the pagination in a DM channel, but this error is not extremely high-level and shouldn't have any major effects on your node process._
 
 _Another note: you'll want to go into the pagination.js file and search for .setFooter() and change the name Natsuki to whatever name your bot is_

+### Clean Timeout
+
+> util/wait.js
+
+Using Promises, wait an amount of time before you do something, but not have to deal with pesky setTimeout syntax, especially when you don't want to get way too nested with your code.
+
+```js
+const wait = require('./util/wait');
+
+let m = await message.channel.send("hacking the mainframe...");
+await wait(5000); // time is in ms
+return m.edit("mainframe hacked.");
+```
+
+Or, alternatively, use `.then()` syntax so your whole code doesn't have to wait.
+
+```js
+const wait = require('./util/wait');
+
+let m = await message.channel.send("hacking the mainframe...");
+wait(5000).then(() => {return m.edit("mainframe hacked.");});
+//some other stuff that will happen without waiting for the message to edit
+```
