-   * The existing jobs push translation strings to Transifex daily, and pull completed translations once a week, on Sunday. You can pick your own schedule on the ``cron`` line. It's best to move your new job off of 8PM UTC, so we don't have to worry about the Transifex API rate limit described above.

 #. Connect to the edX VPN to see your two new jobs at https://tools-edx-jenkins.edx.org/job/translations/ . ``push_translations`` extracts the strings from your repo and pushes them to Transifex. ``pull_translations`` pulls the translated strings from Transifex and checks them into your repo. You can test these jobs out by running them manually.
 
+  * The first job you need to run is ``push_translations``. This would create project resource on Transifex if the resource isn't existed yet.

    * If you can't see this page, you might need to be added to the ``jenkins-tools-translation-jobs`` team in GitHub.
