Adding theme/skinning Piwik

I’ve found the templates under plugins/CoreHome/templates.

What is the best way to add our corporate look and feel into Piwik? Should I create a new plugin entirely? Or should I simply hack away at the files in /templates?

You can hack it in Piwik but will lose the modifications when udpating piwik to latest version. We also offer a professional plugin for full rebranding / white labelling, for sale, contact us at: How to - Analytics Platform - Matomo
