+Octoshark.configure({
   db1: { adapter: "sqlite3", database: "db/db1.sqlite" },
   db2: { adapter: "sqlite3", database: "db/db2.sqlite" }
 })

 When we want to do something in the slave database with all ActiveRecord models, then we need to add Octoshark's current or default connection to all models, either by overriding `ActiveRecord:Base.connection` or using a module that we include in all models.
 
 ```ruby
 class ActiveRecord::Base
   def self.connection
+    # Some rake tasks like `rake db:create` does not load initializers,
+    # and because we're overriding ActiveRecord::Base.connection,
+    # we need to make sure Octoshark is configured before using it.
+    Octoshark.configure(configs) unless Octoshark.configured?
+
+    # Return the current connection (from with_connection block) or default one
     Octoshark.current_or_default_connection
   end
 end
