+By default, the entire user profile is serialized to JSON and stored in the session. If this is not desirable, plugins should override these methods and provide alternate methods.
 
 For example, the below code demonstrates storing only the user ID in the session during serialization, and the use of a database to load the full profile out of a database using that id during deserialization.

+The constructor of the class will receive 2 parameters: a StorageConnection configuration, pulled from Composer's global configuration (currently data.json), and a user identity object, as provided by any configured authentication plugin.
 
 The current behavior of Composer is to instantiate a new instance of the storage accessor class each time it is used. As a result, caution must be taken not to undertake expensive operations each time. For example, if a database connection is required, the connection might be implemented as a static member of the class, inside the plugin's init code and made accessible within the plugin module's scope.

+### Bot Project Templates
+
+Add a project template to the list available during the bot creation process. Plugins can bundle arbitrary bundle of content that will be copied into the bot project at create time. The template should contain a functioning bot project, along with any specializations and configuration defaults required to successfully run the project.
+
+#### `composer.addBotTemplate(template)`
+
+```ts
+await composer.addBotTemplate({
+  id: 'name.my.template.bot'
+  name: 'Display Name',
+  description: 'Long description';
+  path: '/path/to/template'
+});
+```
+
+In addition, boilerplate material will also be added to every new bot project. Plugins can bundle additional content that will be copied into every project, regardless of which template is used.

+#### `composer.addBaseTemplate(template)`
