 # Overview
 
-**Lrf** C++ library provides standard interface as well defines data structures and rules for different laser range finder (LRF) software controllers. **Lrf** interface class does nothing, just provides interface and provides methods to encode / decode commands and encode / decode params. Different LRF controllers inherit interface form **Lrf** C++ class. **Lrf.h** file contains list of data structures ([LrfCommand](#lrfcommand-enum) enum, [LrfParam](#lrfparam-enum) enum and [LrfParams](#lrfparams-class-description) class) and [Lrf](#lrf-interface-class-description) class declaration. [LrfCommand](#lrfcommand-enum) enum contains IDs of action commands supported by **Lrf** class. [LrfParam](#lrfparam-enum) enum contains IDs of parameters supported by **Lrf** class. [LrfParams](#lrfparam-enum) class contains fields for LRF parameters values and provides methods to encode/decode and read/write LRF parameters from JSON file. All LRF controllers should include params and commands listed in **Lrf.h** file. **Lrf** interface class depends only on [ConfigReader](https://rapidpixel.constantrobotics.com/docs/service-libraries/config-reader.html) library (provides methods to read / write JSON config files, source code included, Apache 2.0 license). It uses C++17 standard. The library is licensed under the **Apache 2.0** license.
