+Change this:
+
+```js
+server.listen(port, function() {
+  console.log('Express server listening on port ' + server.address().port);
+});
+server.on('error', onError);
+server.on('listening', onListening);
+```
+
+Into this:
+
+```js
+models.sequelize.sync().then(function() {
+  server.listen(port, function() {
+    console.log('Express server listening on port ' + server.address().port);
+    debug('Express server listening on port ' + server.address().port);
+  });
+  server.on('error', onError);
+  server.on('listening', onListening);
+});
+```
+
+Use the model, from anywhere:
+
+```js
+const models = require('../../models');
+
+// ...
+
+models.User.findAll()
+  .then(users => {
+    res.send({
+      users
+    });
+  })
+  .catch(error => {
+    res.status(400).send({
+      error
+    });
+  });
+```
