 ## Introduction
 
-This document describes the main features and principles of the configuration
-language called `UCL` - universal configuration language.
+This repository provides the `C` library for parsing configurations written in `UCL` - universal configuration language. It also provides functions to operate with other formats:
+
+* `JSON`: read, write and pretty format
+* `Messagepack`: read and write
+* `S-Expressions`: read only (canonical form)
+* `Yaml`: limited write support (mainly for compatibility)
 
 If you are looking for the libucl API documentation you can find it at [this page](doc/api.md).
 
 ## Basic structure
 
-UCL is heavily infused by `nginx` configuration as the example of a convenient configuration
-system. However, UCL is fully compatible with `JSON` format and is able to parse json files.
