+# TypeScript Decorator metadata collector
+
+The `.d.ts` format does not preserve information about the Decorators applied to symbols.
+Some tools, such as Angular 2 template compiler, need access to statically analyzable
+information about Decorators, so this library allows programs to produce a `foo.metadata.json`
+to accompany a `foo.d.ts` file, and preserves the information that was lost in the declaration
+emit.
+
