 ## Go syntax support
 
-The priority of `llgo` feature iteration is:
-
-* Popular C/Python libraries
-* Full Go syntax
-* Go standard libraries
-* Popular Go packages
-
 Common Go syntax is already supported. Except for the following, which needs to be improved:
 
-* interface (Limited support)
 * map (Very limited support)
-* panic (Limited support)
 * recover (Not supported yet)
-* defer (Not supported yet)
-* gc (Not supported yet)
 * chan (Not supported yet)
-* goroutine (Not supported yet)
 * generics (Not supported yet)
 
 Here are some examples related to Go syntax:
 
 * [concat](_demo/concat/concat.go): define a variadic function
 * [genints](_demo/genints/genints.go): various forms of closure usage (including C function, recv.method and anonymous function)
+* [errors](_demo/errors/errors.go): demo to implement error interface
+* [defer](_demo/defer/defer.go): defer demo
+* [goroutine](_demo/goroutine/goroutine.go): goroutine demo
+
+
+## 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 .
+```
+
+
+## Go packages support
+
+Here are the Go packages that can be imported correctly:
+
+* [unsafe](https://pkg.go.dev/unsafe)
+* [unicode](https://pkg.go.dev/unicode)
+* [unicode/utf8](https://pkg.go.dev/unicode/utf8)
