Getting Mint working in Drupal is now a simple process!
You will need to download the module from http://drupal.org/project/mint and expand into your sites/all/modules directory.
Then on your Drupal site, go to Administer > Site Building > Modules and enable the Mint module under the Statistics heading.
Once the module is enabled, go to Administer > Site Configuration > Mint and provide the location of your Mint install. Here you can also enable integration with Official Pepper.
Currently, only the Secret Crush Pepper is supported, however BirdFeeder integration is being worked on at present.
If you have any feedback or requests for integration, please use the Drupal Mint issue queue.
Please note that the module is unlikely to support Third Party Pepper directly — they can be supported by creating other Modules however.
