 Similarities and distance Calculator among Vectors.
 
-## Description
+## :speaking_head: Description
 
 There are several algorithms to calculate the similarities of two bectors; however, no commands are exists treats them.
 `scv` standardizes the interface for calculating the similarities and distances among vectors.
