 To deprecate a formula, add a `deprecate!` call. This call should include a deprecation date (in the ISO 8601 format) and a deprecation reason:
 
 ```ruby
-deprecate! date: "YYYY-MM-DD", because: :reason
+deprecate! date: "YYYY-MM-DD", because: :reason, deprecation_period: :short
 ```
 
 The `date` parameter should be set to the date that the deprecation period should begin, which is usually today's date. If the `date` parameter is set to a date in the future, the formula will not become deprecated until that date. This can be useful if the upstream developers have indicated a date when the project or version will stop being supported. Do not backdate the `date` parameter as it causes confusion for users and maintainers.
 
 The `because` parameter can be a preset reason (using a symbol) or a custom reason. See the [Deprecate and Disable Reasons](#deprecate-and-disable-reasons) section below for more details about the `because` parameter.
 
+The `deprecation_period:` can be either :short or :long (1 or 6 months). After this period a formula should be disabled.

 ## Disabling
 
 If a user attempts to install a disabled formula, they will be shown an error message and the install will fail.
