 ## Prehistory
 This CLI program provides functions for maintaining order on a server or home computer.
 
-The author was tired of watching how a dump is constantly formed in his Downloads directory (and not only) and he decided to end it.
+> How tired I am of looking at this trash in Downloads.  
+> (c) Author
 
-For this purpose this program was developed in the Python language.
+To fix this problem this program was developed in the Python language.
 
-In fact, this program is a working prototype for a similar program in golang, but you can already use it now.

-You can download it and enjoy
+Enjoy.
 
 
 ## How to use
 The program provides three functions:  
-**Cleaning**  
-**Grouping**  
-**Archiving**
+1. **Cleaning**  
+2. **Grouping**  
+3. **Archiving**
 
 In case the first and third functions are already familiar, grouping may seem like an interesting function.
 
-### In order  
+**It is important to close slashes.**
+
+### Examples 
 **Cleaning**  
 `butler.exe --clean /path/to/dir/`  
-Clean target dir. It is important to close slash.
+Clean target dir but not delete it.
 
 **Grouping**  
 `butler.exe --dir /path/to/dir/`  
 Group up files by extensions to new directory named *ALL*.*EXT*.  
 For example, you have a lot of *.exe* files, after this command you will have one directory called *ALL.EXE* with all your *.exe* files in it.
-It is important to close slash.
 
 **Archiving**  
 `butler.exe --archive /path/to/dir/`  
-Create zip archive in current directory for target directory. It is important to close slash.
+Create zip archive in current directory for target directory.
