 # lb2
 
-Implemented several load-balancing algorithms:
+lb2 is an asynchronous multithreaded load balancer written in C++. It is designed to be highly configurable and supports six different algorithms of load balancing. This project aims to provide a flexible and efficient solution for distributing network traffic across multiple servers.
+
+## Supported algorithms
 * `round-robin`
 * `weighted round-robin`
 * `ip-hash`
 * `consistent hash`
 * `least-connections`
+* `least-response-time`
 
 # Installation:
 
+First of all make sure, that `pip` is installed. It will be used for installing `CMake` and `Conan` if needed.
+
+> To automatically install all dependencies and build application type:
+
 ```bash
 ./lbbuild.sh build Release
 ```
 
+This script builds app and copies `configs` folder to ``` build/lb2/configs```
+
+> To build and run unit tests type:
+
+```bash
+./lbbuild.sh test Release
+```
+

+
+# Run app
+
+* Firstly, build app. To do it type: ```./lbbuild.sh build Release```
+
+* Then, go to ```build/lb2/```
+
+* Modify configs in ```build/lb2/configs/config.yaml``` or write your own.
+
+* Run app using: ```./lb_app```
