+# Adapter Manager
+
+A manager for retrieving custom "adapters" - can be used to abstract away from custom implementations
+
+## Install
+
+`npm install @tryghost/adapter-manager --save`
+
+or
+
+`yarn add @tryghost/adapter-manager`
+
+
+## Usage
+
+```js
+const AdapterManager = require('@tryghost/adapter-manager');
+
+const adapterManager = new AdapterManager({
+    pathsToAdapters: [
+        '/path/to/custom/adapters',
+        '/path/to/default/adapters'
+    ]
+});
+
+class MailAdapterBase {
+    someMethod() {}
+}
+
+adapterManager.register('mail', MailAdapterBase);
+
+const mailAdapterInstance = adapterManager.getAdapter('mail', 'direct', mailConfig);
+
+mailAdapterInstance.someMethod();
+```
+
+
+## Develop
+
+This is a mono repository, managed with [lerna](https://lernajs.io/).
+
+Follow the instructions for the top-level repo.
