 In the [Example](Example/) directory, you'll find a "Notes" example app demonstrating ObjectBox's Swift API.
 The example comes with two apps: one for iOS and one for macOS. The iOS example is a full GUI application, whereas the macOS example runs a few operations and then exits.

-Development
------------
+## Development
+
 The source code for ObjectBox's Swift binding can be found [in the Source folder](Source/README.md) of this repository.
 
-Background: code generation
----------------------------
+## Background: code generation
+
 ObjectBox Swift Database generates code at build time for optimal performance at runtime by avoiding reflection etc.
 This is automatically done for you and should be transparent.
 Internally, we use [a fork of Sourcery](https://github.com/objectbox/objectbox-swift-generator) for this.
