-User input interpreter for constructing SQL `WHERE` clause. 
+User input interpreter for constructing SQL `WHERE` clause. Klaus can build complex `WHERE` clauses of variable depth and with different grouping conditions.
 
 ## Documentation
 
-Klaus can build complex queries of variable depth using `AND` and `OR` operators.
-
-`WHERE` clause is constructed using:
-
-* Query – user input.
-* Map – map of user input variable names to the PDO prepared statement named placeholders.
-
-### Query
+### Preparing Query
 
 Raw query consists of the grouping operator definition (`AND` or `OR`) and condition. There are two types of conditions:
 
 #### Comparison Condition
 
-Comparison consists of user input name, value and the comparison operator.

+### Mapping Using Input
 
 Mapping is used to restrict columns that can be included in the query, as well as to provide support for columns that depend on alias or even more complicated constructs.
