 This is my first ever project in Rust so probably a lot of things are not being written in the most optimal way.
 
 ## Why?
-In internet exists a lot of tools to find duplicates, empty folders, temporary files etc. but in most cases there are only available on CLI, which is hard to use by users.  
-GUI FSlint allows to really easy select different files and folders, but is based on old and unsupported Python 2 and GTK 2.

 Other tools are mostly written in C/C++ to provide big performance but still needs to be tested a lot if not contains memory leaks, invalid memory reads/write and double frees.
 
+But the most important thing for me was to learn Rust and create a program useful for the open source community.

 ## Features
 - Written in fast and memory safe Rust
 - CLI frontend, very fast and powerful with rich help

 ## How it works?
 ### Duplicate Finder
 The only required parameter for checking duplicates is included folders `-i`. This parameter validates provided folders - which must have absolute path(without ~ and other similar symbols at the beginning), not contains *(wildcard), be dir(not file or symlink), exists. Later same things are done with excluded folders `-e`.
