 Who are we?
 -----------
 
-We are a group of people passionate about data structures and algorithms. We eye for implementing all the data structures given [here](https://en.wikipedia.org/wiki/List_of_data_structures). We aim for distributing the package among enthusiastic programmers so that they don't have to implement complex data structures in their day to day tasks.

 How are we different?
 ---------------------
 
-There are many pre-exisiting packages available in the open source world for the said task. However, we plan to implement those data structures which are used by both sports programmers as well as the developers. Currently, to the best of our knowledge, no such dedicated attempt has been made. In fact, we will keep each data strucutres independent from other for easy code reusability.
+There are many pre-exisiting packages available in the open source world based on the above idea. However, they lack the implementation of complex data structures and this makes us different. If you have worked with C++ and Python then you know how hard it is to code bug free AVL trees :-).Well, after this project you will not have to worry about it. In fact, we will keep each data structure independent from each other for easy code reusability.
