-### How to use
+## How to use
 
 ```go
 go get github.com/bxelab/runestone@latest
 ```
 
+### Etching
+
+Define a new Rune named *STUDYZY.GMAIL.COM* 
+
+```go
+func testEtching() {
+	runeName := "STUDYZY.GMAIL.COM"
+	symbol := '曾'
+	myRune, err := runestone.SpacedRuneFromString(runeName)
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	amt := uint128.From64(666666)
+	ca := uint128.From64(21000000)
+	etching := &runestone.Etching{
+		Rune:    &myRune.Rune,
+		Spacers: &myRune.Spacers,
+		Symbol:  &symbol,
+		Terms: &runestone.Terms{
+			Amount: &amt,
+			Cap:    &ca,
+		},
+	}
+	r := runestone.Runestone{Etching: etching}
+	data, err := r.Encipher()
+	if err != nil {
+		fmt.Println(err)
+	}
+	fmt.Printf("Etching data: 0x%x\n", data)
+	dataString, _ := txscript.DisasmString(data)
+	fmt.Printf("Etching Script: %s\n", dataString)
+}
+```
+
+### Mint
+
+```go
+func testMint() {
+	runeIdStr := "2609649:946"
+	runeId, _ := runestone.RuneIdFromString(runeIdStr)
+	r := runestone.Runestone{Mint: runeId}
+	data, err := r.Encipher()
+	if err != nil {
+		fmt.Println(err)
+	}
+	fmt.Printf("Mint Rune[%s] data: 0x%x\n", runeIdStr, data)
+	dataString, _ := txscript.DisasmString(data)
+	fmt.Printf("Mint Script: %s\n", dataString)
+}
+```
+
+### Decode
+
+```go
+func testDecode() {
+	data, _ := hex.DecodeString("140114001600") //Mint UNCOMMON•GOODS
+	var tx wire.MsgTx
+	builder := txscript.NewScriptBuilder()
+	// Push opcode OP_RETURN
+	builder.AddOp(txscript.OP_RETURN)
+	// Push MAGIC_NUMBER
+	builder.AddOp(runestone.MAGIC_NUMBER)
+	// Push payload
+	builder.AddData(data)
+	pkScript, _ := builder.Script()
+	txOut := wire.NewTxOut(0, pkScript)
+	tx.AddTxOut(txOut)
+	r := &runestone.Runestone{}
+	artifact, err := r.Decipher(&tx)
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	a, _ := json.Marshal(artifact)
+	fmt.Printf("Artifact: %s\n", string(a))
+}
+```
