+Otter is a pure Swift SQL compiler that allow developers to simply write plain SQL with compile time safety.
+If your database schema changes, you will get compile time errors for the places that need to be fixed.
+It just doesn't generate the code to talk to SQLite, but rather your entire data layer in a testable
+flexible manner. No more writing mocks or wrappers. Just pass in the query.

+Otter is built with testing in mind. Dependency injection is possible right out of the box.
+No need to wrap your database in repositories. Just pass in the `any <Name>Query` and
+you can pass in `Queries.Just`, `Queries.Fail` or even `Queries.Test` for call counts.
+```swift
+class ViewModel {
+  let selectTodos: any SelectTodosQuery

+let live = ViewModel(selectTodos: db.todoQueries.selectTodos)
+
+let test = ViewModel(selectTodos: Queries.Just([...]))
+```

 ### Or Use the Swift Macro
 Otter can even run within a Swift macro by adding the `@Database` macro to a `struct`.

 ## Upcoming Features
 Otter is a young project and there are a lot of new features and functionality I want to add.
 Below are some idea that I would love input on!
+- LSP and vscode plugin
 - Support for multiple statements in a single query
 - Kotlin library/generation
   - Generating Kotlin would allow SQLite based apps to basically share their model/data layer

 - Queries with multiple statements
   - Would allow for easier loading of more complex models that have many joins
   - Want to allow other queries to be called from within the body to help centrize logic.
