Hi, Github fork and star button is added on side-bar of official website in PR#23 https://github.com/apache/incubator-iotdb-website/pull/23 <https://github.com/apache/incubator-iotdb-website/pull/23>;
To get the button and fork / star number, I import GithubButton from vue-github-button module. So next time before built the website on local PC, npm install is needed. Best Regards, ------------------ Zesong Sun
