+## Summer
+
+In order to keep my mind fresh on this, I plan to spend an average of about an hour per week over the summer on this. Some potential summer tasks:
+
+- Design a complete C API, including a way to define classes
+  - Maybe implement part or all of it?
+- Design a standard library using that C API
+- Add basic collection types (issue #5)
+  - At minimum, lists/arrays and dictionaries
+- ???
+
+## Backlog
+
+The backlog has been moved to [this page](Backlog) and expanded to include potential future tasks for later implementation.
