+### app.override(server)
+
+Allows to override the instance of the server for each loading
+plugin. It allows the creation of an inheritance chain for the
+server instances.

+```js
+const boot = require('avvio')
+const assert = require('assert')
+const server = { count: 0 }
+const app = boot(server)
+
+console.log(app !== server, 'override must be set on the Avvio instance')
