+Generals of game
+----------------
+
+This is **an engine that can acts as server and client**, it has **two main components**: 
+
+1. the **games** (that contains the mods and definition of how to play) and 
+2. the **world** (that contains the creeated and playable data). 
+
+Paths places of those are in the [Paths](#paths) sections of this file.
+
+Players used the client role of the program, that joins to a server that can be the same invoked 
+or a remote server, currently many phone clients (apps like minetest that stolen its name) 
+just used those remote servers to play.
