 ## Usage
 
-For all requests made for supabase, you will need to initialize a `SupabaseClient` object.
+To make requests to the `Supabase` database, you will need to initialize a `SupabaseClient` object:
 
 ```swift
 let client = SupabaseClient(supabaseURL: "{ Supabase URL }", supabaseKey: "{ Supabase anonymous Key }")
 ```
 
 ## Login Implementation
 
-Import and Initialize GoTrueSwift which is bundled with Supabase Swift
-```swift
-import GoTrue
-
-//Intialize Gotrue
-var client: GoTrueClient = GoTrueClient(url: "{ Supabase URL }", headers: ["apikey": { Supabase anonymous Key }])
-```
+Inside the `SupabaseClient` instance created before, you can find an `auth` property of type `GoTrueClient`. You can use it to perform sign in and sign up requests.
