+
+#### Why?
+
+First of all, many people have asked about donation, so here it is!
+
+Second, in all good conscience, the most of the visible costs are covered by us, like the domain and server. We also spend a tremendous time to make Hexo running and functioning. This is the real cost and also invisible. 
+
+#### Benefits?!
+
+We thank for every penny donations, here is a list of benefits you and us can achieve:
+
+1. Covers our cost.
+2. Motivate and admit our work.
+3. List your name on Hexo.io website (2.5k users and 10k pageviews per day)!
+
+There are two tiers of donation: 
+  * Less than $100, your name and website link will be on the donator list.
+  * More than $100, your name, icon, and website link will be on the home page for at least one month (depend on the amount).
+
+** Again, thanks for your support! **
