+## Production like
 
-## start worker instance
+start worker instance
 
 To start a current worker instance:
 
 ```sh
 python3 -m celery worker --app=swh.scheduler.celery_backend.config.app \
                 --pool=prefork \
                 --concurrency=10 \
                 -Ofair \
                 --loglevel=debug 2>&1
 ```
 
 ## Produce a repository to load
 
 You can see:
 
 `python3 -m swh.loader.svn.producer svn --help`
 
 ### one repository
 ```sh
 python3 -u -m swh.loader.svn.producer svn --svn-url file:///home/storage/svn/repos/pkg-fox --visit-date 'Tue, 3 May 2017 17:16:32 +0200'
 ```
 
 Note:
 - `--visit-date` to override the default visit-date to now.
 
 ### multiple repositories
 
 ```sh
 cat ~/svn-repository-list | python3 -m swh.loader.svn.producer svn
 ```
 
 The file svn-repository-list contains a list of svn repository urls
 (one per line), something like:
 
 ```txt
 svn://svn.debian.org/svn/pkg-fox/ optional-url
 svn://svn.debian.org/svn/glibc-bsd/ optional-url
 svn://svn.debian.org/svn/pkg-voip/ optional-url
 svn://svn.debian.org/svn/python-modules/ optional-url
 svn://svn.debian.org/svn/pkg-gnome/ optional-url
 ```
 
 ## Produce archive of svndumps list to load
 
 see. `python3 -m swh.loader.svn.producer svn-archive --help`
