 If you're using Xcode, [use this guide](https://developer.apple.com/documentation/swift_packages/adding_package_dependencies_to_your_app) to add `supabase-swift` to your project. Use `https://github.com/supabase/supabase-swift.git` for the url when Xcode asks.
+
+## Usage
+
+For all requests made for supabase, you will need to initialize a `Supabase` object.
+```swift
+let client = Supabase(supabaseUrl: "{ Supabase URL }", supabaseKey: "{ Supabase anonymous Key }")
+```
+This client object will be used for all the following examples.
+
+### Database
+
+Query todo table for all completed todos.
+```swift
+do {
+   let query = try client.database.from("todos")
+                                .select()
+                                .eq(column: "isDone", value: "true")
+                                
+   try query.execute { [weak self] (results) in
+       guard let self = self else { return }
+
+       // Handle results
+   }
+} catch {
+   print("Error querying for todos: \(error)")
+}
+```
+
+Insert a todo into the database.
+```swift
+struct Todo: Codable {
+    var id: UUID = UUID()
+    var label: String
+    var isDone: Bool = false
+}
+
+let todo = Todo(label: "Example todo!")
+
+do {
+    let jsonData: Data = try JSONEncoder().encode(todo)
+    let jsonDict: [String: Any] = try JSONSerialization.jsonObject(with: jsonData, options: .allowFragments))
+    
+    try client.database.from("todos")    
+                       .insert(values: jsonDict)
+                       .execute { results in
+        // Handle response
+    }
+} catch {
+   print("Error inserting the todo: \(error)")
+}
+```
+
+For more query examples visit [the Javascript docs](https://supabase.io/docs/reference/javascript/select) to learn more. The API design is a near 1:1 match.
+
+Execute an RPC
+```swift
+do {
+    try client.database.rpc(fn: "testFunction", parameters: nil).execute { result in
+        // Handle result
+    }
+} catch {
+   print("Error executing the RPC: \(error)")
+}
+```
