Provide an icon support site

[DrZhangjilin]

Hi,

I like the theme very much, and I am trying to build my own personalized blog recently. However, I encountered a problem. I added a new social networking site to introduction.html, but the corresponding icon could not be displayed in the webpage preview. I learned in a question that the theme of Avicenna is based on feathericons, and the new icon I use is based on iconfont. I don't know how to add new icons.

In addition, I sincerely hope that the author will include iconfont in the icon system, because it supports more than 20 million icon styles and is convenient for users to customize and modify.
Thanks!
