+# Czkawka
+Czkawka is simple and easy to use alternative to Fslint written in Rust.  
+It is in very early development, so most of the functions aren't added and doesn't work.  
+
+
+## Done
+- Nothing now
+
+## TODO
+- Graphical UI(GTK)
+- Duplicated file finding
+- Setting include and exclude directories(Regex support needed)
+- Removing empty folders
+- Files with debug symbols
+
+## License
+Czkawka is released under the terms of the GNU Lesser General Public License, version 2.1 or, at your option, any later version, as published by the Free Software Foundation.
