 ### Configuration of the Makefile
 
-The file `global-config.mk` contain configuration informations about paths to sources, executables and to the building destinations. It details all the variables which can be set but shouldn’t be modified, as it can receive new variables in the future needed for the script to work. Moreover is handled by git for new versions and any changes you make would be erased by new pull of the script. If you want to specify a dedicated value to any variable, you should copy its line definition to a new file inf the same folder, called `local-config.mk`. Like this, you will keep your local configuration files in the future with new versions of the script.
+The file `global-config.mk` contain configuration informations about paths to sources, executables and to the building destinations. It details all the variables which can be set but shouldn’t be modified, as it can receive new variables in the future needed for the script to work and concerns only example files included with the script. Moreover is handled by git for new versions and any changes you make would be erased by new pull of the script. To specify dedicated values to any variable, you should copy its line definition to a new file inf the same folder, called `local-config.mk`. Like this, you will keep your local configuration files in the future with new versions of the script. You will have to do it at least to take in charge your persnal data and not the `example` content given.
 
 Simply write either the absolute or the relative path from your Makefile script situation for any information needed.
 
-## Executables used
-
-These are the adress of the substance automation toolkit binaries.
-
 ## Sbsar files generation part
 
 You need to define a sbs source folder where the script will check for new content in the `SBS_DIR` variables content.
 
 You must write down also the place where the script will write the generated sbsar.
 
+## Executables used
+
+These are the adress of the substance automation toolkit binaries. Note you can use former variables defined sooner in the file, like it is done in the `--includes` section of MAKESBSAR.
+
 ## Texturesets files
 
 This files will be used only internally by the script to check the texturesets it handles.
