+## How to customize
+There are several hooks to customize the behavior of the go-restful package.
+
+- Router algorithm
+- Panic recovery
+- JSON decoder
+- Trace logging
+- Compression
+- Encoders for other serializers
+- Use [jsoniter](https://github.com/json-iterator/go) by build this package using a tag, e.g. `go build -tags=jsoniter .`
+
+TODO: write examples of these.
