Ayuda a Configurar un Plug-in

Compre una Plug-in para Wordpress y necesito ayuda para confirgurarlo ya que no entiendo unos comandos que hay que realizar, segun la explicación que me dan en su manual tengo que realizar estos pasos. If you want to use a cron job, you can perform scheduled updates by sending regularly-scheduled requests to [login to view URL] For example, inserting the following line in your crontab:*/30 * * * * /usr/bin/curl --silent [login to view URL] run in every 30 minutes and check for new jobs to save as post. If you can't use Cron, just call the following link in your browser periodically: [login to view URL]; You can also specify the parameters in the url:  [login to view URL];location=New%20York&country_code=US&keyword=Manager  By default, the job feed coming from Indeed, but you can also specify the service provider:  [login to view URL];location=New%20York&country_code=US&keyword=Manager&service=careerjet  or:  [login to view URL];location=New%20York&country_code=US&keyword=Manager&service=indeed  The Indeed Policy doesn't allow to make cache about the jobs, therefore you use it for your own risk. If you don't store the jobs for a long time, it can be ok. CareerJet can block your account when you make too much API calls, if it is happened, contact with them and they will release your blocked account and increase your limits. You can include jobs directly from these service providers without caching the jobs with simple shortcodes, to check how can you use those, please see the USING SHORTCODES section.
