 The script runs one instance of DRAMSys for each of the files in the list.
 **The multiple instances run in parallel**.
 
+Set the variable **use_DRAMSyrup_to_generate_config_files** to **yes** in
+order to get all the essential simuation files auto generated from a
+description in JSON format loaded from
+[**configs.json**](DRAMSys/library/resources/scripts/DRAMSylva/configs.json).
+
+``` bash
+use_DRAMSyrup_to_generate_config_files="yes"
+```
+
++ Insert the desired simulation data in **configs.json**. Multiple arrays are
+  allowed and encouraged. Each array corresponds to a full simulation setup.
++ Commit and push your changes.
++ Run **DRAMSylva** as previously described. All generated files will be
+  inside the output folder, so it will be possible to keep a perfect track of
+  all simulations.
+
+
 For more information check the documentation in [DRAMSylva folder](DRAMSys/library/resources/scripts/DRAMSylva).
