 This project is based on collaborative work with [@inlife](https://github.com/inlife) and inherited all the features of the original [fork](https://github.com/zpl-c/enet). This version is extended and optimized to run safely in the managed .NET environment with the highest possible performance.
 
+Building
+--------

 --------
 Before starting to work, the library should be initialized using `ENet.Library.Initialize();` function.
