 ## Overview
 
-The repository is a collection of open-source implementation of a variety of algorithms implemented in C++ and licensed under [MIT License](https://github.com/TheAlgorithms/C-Plus-Plus/blob/master/LICENSE). The algorithms span a variety of topics from computer science, mathematics and statistics, data science, machine learning, engineering, etc.. The implementations and the associated documentation are meant to provide a learning resource for educators and students. Hence, one may find more than one implementation for the same objective but using a different algorithm strategies and optimizations.

 ## Features
 
 * The repository provides implementations of various algorithms in one of the most fundamental general purpose languages - [C++](https://en.wikipedia.org/wiki/C%2B%2B).
 * Well documented source code with detailed explanations provide a valuable resource for educators and students alike.
-* Each source code is atomic using [STL classes](https://en.wikipedia.org/wiki/Standard_Template_Library) and _no external libraries_ are required for their compilation and execution. Thus the fundamentals of the algorithms can be studied in much depth.

 * Source codes are [compiled and tested](https://github.com/TheAlgorithms/C-Plus-Plus/actions?query=workflow%3A%22Awesome+CI+Workflow%22) for every commit on the latest versions of three major operating systems viz., Windows, MacOS and Ubuntu (Linux) using MSVC 16 2019, AppleClang 11.0 and GNU 7.5.0 respectively. 
 * Strict adherence to [C++11](https://en.wikipedia.org/wiki/C%2B%2B11) standard ensures portability of code to embedded systems as well like ESP32, ARM Cortex, etc. with little to no changes.
 * Self-checks within programs ensure correct implementations with confidence.
