 # RogueSquadron Data Extractor - TEXTURE module
 
+Inspired by the work **dpethes** (https://github.com/dpethes/rerogue)
+
 This set of git repos are a compilation of tools coded in C to make RS modding far more than a dream!
 The collection consist of few independants modules, each of them deals with specific data like sound, textures, heightmaps, etc...
 
-This is the **TEXTURE** module.
 
-**CAUTION! This module is in very alpha! Don't use it for the moment.**
+
+All modules are independants. This is the **'TEXTURE'** module.
+
+**CAUTION! Master branch is hugely buggy and should not be used, please take only released versions.**
 
 ## TEXTURE MODULE
 
 It's extract texture datas from Rogue Squadron 3D (PC) game files (DAT).
 
+### Using
+
+*TODO...*
+
 ### Dependencies
 
-- zlib (1.2.3)
+Necessary libs for running (provided in release) and for compiling.
-- libpng (1.2.37)
+
+- zlib (1.2.11)
+- libpng (1.6.37)
 
 ### Compiling
 
 You can compile on both Windows or Linux system, you only need to adjust your dependencies.
 *Makefile is coming...*

-### Using
