+## Build without `MsgPack` rendering feature
+
+Gin enables `MsgPack` rendering feature by default. But you can disable this feature by specifying `nomsgpack` build tag.
+
+```sh
+$ go build -tags=nomsgpack .
+```
+
+This is useful to reduce the binary size of executable files. See the [detail information](https://github.com/gin-gonic/gin/pull/1852).

 ## API Examples
 
 You can find a number of ready-to-run examples at [Gin examples repository](https://github.com/gin-gonic/examples).
