 Key features of Dependency Injector
 -----------------------------------
+
+*Dependency Injector* is a dependency injection framework for Python projects. 
+It was designed to be unified, developer-friendly tool for managing any kind
+of Python objects and their dependencies in formal, pretty way.
+
+*Dependency Injector* framework key features are:
+
++ Easy, smart, pythonic style.
++ Obvious, clear structure.
++ Extensibility and flexibility.
++ Memory efficiency.
++ Thread safety.
++ Documentation.
++ Semantic versioning.
+
+*Dependency Injector* framework could be used in different application types:
+
++ Web applications based on Flask, Django or any other web framework.
++ Asyncronous applications based on asyncio, Tornado and Twisted.
++ Standalone frameworks and libraries.
++ GUI applications.
+
+*Dependency Injector* framework could be integrated on different project 
+stages:
+
++ It could be used in the beginning of development of new applications.
++ It could be integrated into applications that are in active development 
+  stage.
++ It could be used for refactoring of legacy applications.
+
+Components of *Dependency Injector* framework could be used:
+
++ In composition with each other.
++ Separately between each other.
+
+Main idea of *Dependency Injector* framework is to be useful tool for the 
+right thing.
