+### Queue manager
+
+We use [`pg-boss`](https://github.com/timgit/pg-boss/blob/master/docs/usage.md#publish) to handle queues. This package exposes an instance of pg-boss, so you don't have to initiate it yourself. In other words, there's no need to use the `start` and `stop` functions. These are handled.
+
+The following SQL code needs to have run on your database, either via a database init script or as part of a migration:
+
+```sql
+CREATE EXTENSION IF NOT EXISTS pgcrypto;
+```
+
+Use the queue manager as follows:
+
+```js
+const { boss } = require('@coko/server')
+
+await boss.publish('my-job', { and: 'how' })
+```
+
+The above method is recommended, but if you already use pubsweet's `connectToJobQueue` and want a low-overhead way to switch to `@coko/server`, we also expose the same function for backwards compatibility.
+
+```js
+// Replace this
+const { connectToJobQueue } = require('pubsweet-server')
+
+// With this
+const { connectToJobQueue } = require('@coko/server')
+```
+
+You can also disable the queue manager altogether with the following config option:
+
+```js
+// config/default.js
+
+module.exports = {
+  'pubsweet-server': {
+    useJobQueue: false,
+  },
+}
+```
+
 ### Disable GraphQL
 
 There are cases where you might not want a graphql server at all. eg. If you are building a sevice with a single REST api endpoint with coko server.
