+# Use DiapOTB Chains
+
+To launch processings chains, only one argument is required as inputs : a configuration file (json format)
+
+
+A interactive script was developped into *utils* package to generate a configuration file following a user's Q&A.
+
+
+Thus to run a chain, you can :
+* Generate a configuration file. A python script helps you to create a new json file by loading examples json file(into <install_directory>/python_src/) and asking for general fields such as input_path or reference image ... . 
+
+*python <install_directory>/python_src/utils/generateConfigFile.py*
+
+* Modify (or keep) the values into your json file (see the description of the selected processing chain)
+
+* Execute the selected chain : 
+
+*python <install_directory>/python_src/<selected_chain>.py <your_json_file>*
