 *Goals:* simple configuration files, which can easily be manually edited by TAs.  These files is then parsed by joj-config-generation script to generate final internal `json` configurations files.
 
 
-## repo level config file
-
-Used to discover what assignment and tasks are requested and where corresponding json config files can be found.
- 
--  `assignments`: list of all assignments in this repo
-- `assignment`: array of table with list of tasks
-
-Example: 
-- 4 assignments
-- no task for 0, tasks 2 3 4 5 and 6 can be tested on joj for h1, etc.
-- tree structure: `h1/2/conf.json`
-- expected joj commit: `feat[h1/2]: joj` or `fix[h2/4]: joj`
