 # Cubosphere [reborn] — data repository
 This repo contain data files for cubosphere. Pretty useless without code.
 
-## How build system works?
-This `CMakeLists.txt` is incuded from code repo one. Then:
-
-* All `raw` folder content will be installed to `DATADIR` as is
-* Data in `zip` folder will be:
-    * handled same way by default
-    * zipped to `native_data.zip` which will be installed as `data000.zip` to `DATADIR` if `-DZIP=TRUE` specified
-
-This is done for easier data editing.
+## How does the build system work?
+This `CMakeLists.txt` is incuded from the code repo one.  Formerly the data was split into different folders based on how it was installed, but now they are all organized in the same structure as the installed data.  This is done for easier development.
 
 ## Other folders
-* `desktop` — linux-specific files for menu (have its own `CMakeLists.txt`)
-* `origins` — some images which are used as source for different files (`.xcf` is recommended format for images).
