 # Model definition
 
-To define mappings between a model and a table, use the `define` method. Sequelize will then automatically add the attributes `createdAt` and `updatedAt` to it. So you will be able to know when the database entry went into the db and when it was updated the last time. If you do not want timestamps on your models, only want some timestamps, or you are working with an existing database where the columns are named something else, jump straight on to [configuration ][0]to see how to do that.
