+## MacroAvailable
+
+All the ideas described in the following apply to all packages that depend on SpryKit, not only macros.
+
+In order to handle breaking API changes, clients can wrap uses of such APIs in conditional compilation clauses that check MacroAvailable.
+
+```swift
+#if canImport(SpryMacroAvailable)
+// code to support @Spryable
+#else
+// code for SpryKit without Macro
+#endif
+```
