+Here is a small piece of code in go to generate the keypair for the backend:
 
 ```go
-func GenerateKey() {
-	privK := suite.Scalar().Pick(suite.RandomStream())
-	pubK := suite.Point().Mul(privK, nil)
+package main
 
-  fmt.Println("PUBLIC_KEY:", pubK)

+
+    fmt.Println("PUBLIC_KEY:", pubK)
 	fmt.Println("PRIVATE_KEY:", privK)
 }
 ```
 
+You can also use the `cli` program to generate the keys:
+
+```sh
+npm run keygen
+```
+
 # Run the program
 
 Once all the previous steps done, the project can be run using `npm start`
