It's great to see the project website is live! I believe we should include ASF-related branding and project descriptions on the homepage to better comply with ASF's branding guidelines for incubator projects. @goodjava @sadadw1 @shanwb

很高兴看到项目网站上线！我觉得我们应该在网站首页加上有关于ASF的相关品牌和项目说明，符合ASF对于孵化项目在品牌展示上的规定。
