 # go-base16384
 base16384 interface of golang
+
+# Functions
+
+## func Encode(b []byte) []byte
+Encode b to utf16be.
+## func Decode(b []byte) []byte
+Decode from encoded b.
+## func UTF16be2utf8(b []byte) ([]byte, error)
+Display the result.
+## func UTF82utf16be(b []byte) ([]byte, error)
+Turn the result to its original coding form to decode.
+
+# Usage
+## As package
+Just include it in your project.
+## As lib
+Copy this repo to `$GOPATH/src`, then execute
+```bash
+go install -buildmode=shared -linkshared std
+go install -buildmode=shared -linkshared base14
+```
+Now you can use
+```bash
+go build -linkshared ...
+```
