Activerse installed. Remember to use the initializer file to create your desired credentials structure. You may run

rails g activerse:fill

to fill out your credentials file. Addition made into the initializer will reflect on the credentials file upon reissuing this command.

You may want to regenerate your master key with

rake activerse:regenkeys

or generate fresh credentials with

EDITOR="vim" rails credentials:edit

Remember that either your config/credentials.yml.enc and your config/master.key files *must not* be under source control.
