Recently dubbo held an offline meetup. When discussing with many participants, many people have suggested that dubbo has very few comments.
Comments are very important for us to understand the code. If our comments are few, it is very unfriendly for new developers. I created a new issue[1] to track this. We need more developers to contribute notes. I will continue to follow up on this matter. [1] https://github.com/apache/incubator-dubbo/issues/2884
