+## Defer
+
+LLGo defer does not support usage in loops. This is not a bug but a feature, because we think that using defer in a loop is a very unrecommended practice.
+
+
+### Garbage Collection (GC)
+
+By default, LLGo implements `gc` based on [bdwgc](https://www.hboehm.info/gc/) (also known as [libgc](https://www.hboehm.info/gc/)).
+
+However, you can disable gc by specifying the `nogc` tag. For example:
+
+```sh
+llgo run -tags nogc .
