 ## Motivation
 
-It is quite a common task to check if data satisfies specific constraints. For example, server backend must check validity of commands that come from the clients. Another example is a requirement to validate input data entered in the user interface and then show messages describing validation errors.
-
-A typical approach for implementing complex data validation is writing nested *if-conditions* or chained invocations of partial validation methods. Declarations of the constraints could become intermixed with their implementations so that they would spread over the code which makes it hard to maintain them. Requirement to construct and show error messages could make everything still more complicated.
+A common issue when receiving data either by application from user interface or by server remotely from clients is verifying data integrity and/or specific constraints. A typical approach for implementing complex data validation is writing nested *if-conditions* or chained invocations of partial validation methods. Declarations of the constraints could become intermixed with their implementations. Thus, validation would spread over the code which makes it hard to maintain it. Requirement to construct and show error messages could make everything still more complicated.
 
 `cpp-validator` library allows one to declare data constraints with clean statements in certain points of code and apply them in other points of code on demand. If needed, the validation error messages are automatically constructed by taking into account the user's locale.
