 # A little tool to feature Steam's miniprofile on your website 
 
+### Now come with an interactive builder: https://gamer2810.github.io/miniprofile-builder/
+
 This is a tool that loads your miniprofile(*with animated background and frame*) as a HTML entity so that you can feature it on your website.
 
 This tool only shows **PUBLIC** information of your Steam account and therefore **DOES NOT NEED your Steam's API KEY or CREDENTIALS**.
