 Software chunks initially developped for **ID02 upgrade program** in 2012-2014.
 
 Dahu is a lightweight plugin based framework...
-   ... technically a JSON-RPC server over Tango
+   ... technically a JSON-RPC server over Tango:
+
 * plugins can be class or can be generated from any state-less function written in Python
 * a plugin is executed within a job, each job lives in its own thread.
 * plugins have empty constructors plus 4 methods (or more)
+
  - `setup` allows to set the input parameters. Sanitization is performed here.
  - `process` does the work.
  - `teardown` sets the output, the logging and cleans up (if needed).
  - `abort` can be used to stop the processing if a plugin is a daemon.
+
 * the job is responsible for serializing on disk of the plugin's input and output
 * jobs can be launched using the tango interface (or other ...)
 * plugins have a single input and output, they are simple JSON-serializable dictionaries.
