Sugar Developer Guide 12.0
The Sugar Developer Guide describes how to configure and customize Sugar by making code- and database-level changes to the Sugar file system. You will need direct access to the server along with the proper file-system permissions to alter files in the Sugar instance directory.
Sugar customers that are hosted on Sugar's cloud service cannot directly access their database's file system but can work with a Certified Sugar Partner to customize their Sugar deployment. For a list of Certified Sugar Partners, please refer to the Partner Page to find a reselling partner to help with your development needs.
