SuiteCRM vs SugarCRM ( from coding view )


my company is testing out / evaluating suiteCRM. As of now I was doing evaluation for functionality / cost / integration / customization. Looking for documentation ( developer and admin ) I found that most of the documents are from sugarCRM, not suiteCRM. I know this is because it was based off the latter. Is there any clear cut documentation purely for suiteCRM? If not, should I still be fine just studying / going through the sugarCRM developers guide to work with suiteCRM?

kind regards
