-## Garbage Collection
+# Garbage Collection
+
+## Initiation Task
+
+1. Move `shared_head` to `shared_mark_head`
+2. Add a mark task to each of the threads
+
+## Mark Task(s)
+
+1. Run gc interface on each task in the queue
+2. Increase `shared_threads_makred`
+3. If `shared_threads_makred` is equal to `avaiable_threads` schedule sweep task
+
+## Sweep Task
+
+1. Go through `shared_mark_head` freeing anything that is not marked
+2. Add anything left on `shared_mark_head` to `shared_head`
