+## Rating Algorithms 
 Each metric defined below has its own specific API query. The process is simple : we fetch the data from GitHub APIs which is already streamlined for a specific metric, cut down the data further (if needed) and then assign appropriate weights to these numbers to form a score of a User or a Repo.

-### User Rating
+## User Rating
 A total of 5 metrics have been designed to rate the user and the algorithms are designed according to the process mentioned above.
 
 Each score is a boundless score calculated by summation of weighted sums of each of the following metric.
