 SteamPress is easy to integrate with your application. There are two providers that provide implementations for [PostgreSQL](https://github.com/brokenhandsio/steampress-fluent-postgres) or [MySQL](https://github.com/brokenhandsio/steampress-fluent-mysql). You are also free to write your own integrations. Normally you'd choose one of the implementations as that provides repository integrations for the database. In this example, we're using Postgres.
 
 First, add the provider to your `Package.swift` dependencies:

 This will register the routes for you. You must provide implementations for the different repository types to your services:
 
 ```swift
-services.register(MyTagRepository(), as: BlogTagRepository.self)
-services.register(MyUserRepository(), as: BlogUserRepository.self)
-services.register(MyPostRepository(), as: BlogPostRepository.self)
+app.steampress.blogRepositories.use { application in
+    MyRepository(application: application)

 ```
 
-You can then register the SteamPress provider with your services:
-
-```swift
-let steampressProvider = SteamPress.Provider()
-try services.register(steampressProvider)
-```
+SteamPress will be automatically registered, depending on the configuration provided (see below).
 
 ## Integration
 
 SteamPress offers a 'Remember Me' functionality when logging in to extend the duration of the session. In order for this to work, you must register the middleware:
 
 ```swift
-var middlewares = MiddlewareConfig()
-// ...
-middlewares.use(BlogRememberMeMiddleware.self)
-middlewares.use(SessionsMiddleware.self)
-services.register(middlewares)
+application.middlewares.use(BlogRememberMeMiddleware())
 ```
 
 **Note:** This must be registered before you register the `SessionsMiddleware`.
 
-SteamPress uses a `PasswordVerifier` protocol to check passwords. Vapor doesn't provide a default BCrypt implementation for this, so you must register this yourself:
-
-```swift
-config.prefer(BCryptDigest.self, for: PasswordVerifier.self)
-```
+**TODO: Update**
 
 Finally, if you wish to use the `#markdown()` tag with your blog Leaf templates, you must register this. There's also a paginator tag, to make pagination easy:
 
 ```swift
- var tags = LeafTagConfig.default()
+var tags = LeafTagConfig.default()
 tags.use(Markdown(), as: "markdown")
 let paginatorTag = PaginatorTag(paginationLabel: "Blog Posts")
 tags.use(paginatorTag, as: PaginatorTag.name)

 Additionally, you should set the `WEBSITE_URL` environment variable to the root address of your website, e.g. `https://www.steampress.io`. This is used to set various parameters throughout SteamPress.
