"\n" +
"### 共享意味着什么\n" +
"\n" +
"一旦你共享了一本书，就会使用你的社区账号自动发一篇书籍共享帖，这意味着你做了一个**承诺**：将书送到需要的人手中。如果有同城的书籍需求者回帖，就面交吧！\n" +
"\n" +
"### 如何参与\n" +
"\n" +
"1. 使用微信扫描如下二维码，进入黑客派社区小程序\n" +
"  \n" +
"2. 按照小程序的指引开始即可\n" +
"\n" +
"### 一点思考\n" +
"\n" +
"类似共享书籍的事情有很多人做过，比如：\n" +
"\n" +
"* 摆摆书架\n" +
"* 青番茄\n" +
"* 书巢\n" +
"* 丢书大作战\n" +
"* 很多社区的书籍交换\n" +
"\n" +
"大家的出发点都是想让这个世界变得更好。黑客派的『书单』将作为长期活动持续下去，大家随时都能参与进来，让你我的生活变得更丰富有趣！");
