 ## What's up?
 
-Hey! This is a simple web-service called ![HuffPress](https://img.shields.io/badge/Huff-Press-orange.svg). What it does? Well, actually it *huffpresses* files... I mean, compresses files using the [Huffman compression](https://en.wikipedia.org/wiki/Huffman_coding "Read about it on Wikipedia").
+Hey! This is a simple web-service called __HuffPress__. What it does? Well, actually it _huffpresses_ files... I mean, compresses files using the [Huffman compression](https://en.wikipedia.org/wiki/Huffman_coding 'Read about it on Wikipedia').
+
+Also it uses a bit modified [SHICHIRO coding](https://github.com/H1K0/SHICHIRO 'View on GitHub') for compressing and embedding Huffman table.
 
 ## What do I need?
 
 - Any web browser
 - ![PHP 7+](https://img.shields.io/badge/PHP-7+-blueviolet.svg)
-- ![Python 3+](https://img.shields.io/badge/Python-3+-blue.svg)
-- `click` library
+- ![Python 3.7+](https://img.shields.io/badge/Python-3+-blue.svg)
+- `click` python library
 
 ## So, how do I use it?
 
-I think it's too easy to explain the usage of this service, but anyway here's [a video guide](https://yadi.sk/i/aiy78bDaoKqoJQ "Watch!").
