+- Web3.js
+- Automated Tests using Mocha and Chai
+
+
+## Quick setup and running
+
+- Install node in the local (Node version is v12.18.3 and if possible, use the same version for compatibility).
+- Download Ganache from https://www.trufflesuite.com/ganache and install it in the local.
+- Run Ganache in the local.
+
+``` bash
+$ npm install --g truffle@5.1.39 # If possible, use the same version for compatibility
+
+$ npm install # Or yarn install
+$ npm run truffle-compile # Compile smart contracts
+$ npm run truffle-migrate # (Or npm run truffle-migrate-reset) Deploy the compiled smart contracts
+$ npm run truffle-test # Run the automated tests to make sure of the behaviors of the smart contracts
+$ npm start # Run the UI website
+
+$ npm run truffle-issue-dapp-tokens # Issue Dapp tokens to the stakers
