+## Decorators
 
+One of ways of adjusting input data or customizing module outputs in `teal` is the usage of `transformators` 
+created through `teal_transform_module`. This document will focus on modifying outputs, and for clarity, we will refer 
+to these output-modifying objects as decoration objects or decorators.
 
-## Decorators
+In below chapter we will present how to create the simplest static decorator with just a server part. Later, we will
+present examples on more advanced usage, where decorators contain UI. You will also learn about a convenience

+example module that utilizes decorators and a snippet that uses this module in `teal` application.
