 ## My Website
 
-This is my website. Pretty self-explanatory.
+This is my personal website. I wrote it myself from scratch using [my own
+theme][bobatheme-github] and a static site generator named [Hugo][hugo-website].
+I occasionally write blog posts under the [blog section][blog-section].

-My website uses my own custom theme named
