-As described earlier, a workunit represents the inputs to a computation. The steps in creating a workunit are:
-
-    * Write XML 'template files' that describe the workunit and its corresponding results. Generally the same templates will be used for a large number work of workunits.
-    * Create the workunit's input file(s) and place them in the download directory.
-    * Invoke a BOINC function or script that creates a database record for the workunit. 
-
-Once this is done, BOINC takes over: it creates one or more results for the workunit, distributes them to client hosts, collects the output files, finds a canonical result, assimilates the canonical result, and deletes files.
+To submit a job:

+    * Write XML 'template files' that describe the job's input and outputs (typically the same template files will be used for many jobs).
+    * Create the job's input file(s) in the download directory.
+    * Invoke a BOINC function or script that submits the job.

+Once this is done, BOINC takes over: it creates one or more instances of the job, distributes them to client hosts, collects the output files, finds a canonical instance, assimilates the canonical instance, and deletes files.
 
 During the testing phase of a project, you can use the [http://boinc.berkeley.edu/busy_work.php make_work daemon] to replicate a given workunit as needed to maintain a constant supply of work. This is useful while testing and debugging the application.
