-Moments是一款专门为短博文设计的Hugo主题（插入链接）。开发初衷是在微信朋友圈之外做一个纯粹写给自己的，独立的短文/动态空间，去记录生活点滴，个人思绪，发现与想法。后面发现Moments的使用对象不仅仅可以是自己，还可以是一群人，你可以为是朋友、团队，亦或情侣搭建一个专有的Moments空间。

 Moments is a hugo theme designed for micro-blogging. The original intention is to create a personal space for sharing daily life, thoughts, discoveries & ideas, outside Wechat. Later on, it came to my mind that Moments can be a sharing space not only for a single individual, but also for friends, teams or even couples.
