How to register your Grid Certificate in the LZ VO

* Using a web browser go to the LZ VOMS server 
  ==> Use your grid certificate (signature) to authenticate
* Fill in the form with all the information and click submit
* You should receive an email that tells you to confirm the submission
* A VO representative will approve your ticket only after your confirmation

How to get a Grid User Certificate

* Depending upon the university, research institution or location you have to choose the certification authority
* For USA and other parts of Noth/South America, Open Science Grid (OSG) is the certification authority
* For UK, the equivalent is GridPP
* Follow instructions given on those pages to obtain your grid user certificate

## Copy files from local directory to the storage area
