 ===========================
-See license.txt for license information.
 
-Authors of source code
+Simplified creative for more accurate on mobile or small screens
+
+Information
+------------
+
+This mod is named `creative` and is a replacement for default "creative" mod 
+of orginal game, with reduced tabs, also minenux fork it uses a cached memory 
+to faster lodaing respect settings.
+
+![screenshot.png](screenshot.png)
+
+Technical Information
 ----------------------
+
+This mod fork used as base the commit `72acd4db9cc676f9e0ae1435e371adb2b10cdbe8`, 
+for backguard compatibility with 5.2 and 0.4.16, with minimal backports, you 
+can download from https://codeberg.org/minenux/minetest-mod-creative and after 
+clone or downloaded renamed to `creative` (obviously replace the current one if any)
+
+Modified by TenPlus1 (added creative privilege, reduced tab count, tweaked code), 
+original work is at https://notabug.org/TenPlus1/creative
+
+The minenux fork cut down images to use only text so media download is not a hit!
