 ## JSDocs
-- Avoid docs that don't add any additional information.
+
 - Always document parameters and return values.
-- Method descriptions are optional and should be added when it's not obvious what the purpose of the method is.
-- Use uppercase when referring to JS primitive values (e.g. `Boolean` not `bool`, `Number` not `int`, etc)
+- Optional parameters should be enclosed by `[]` e.g. `@param {String} [optionalText]`.
+- Document object parameters with separate lines e.g. `@param {Object} parameters` followed by `@param {String} parameters.field`.
+- If a parameter accepts more than one type use `*` to denote there is no single type.
+- Use uppercase when referring to JS primitive values (e.g. `Boolean` not `bool`, `Number` not `int`, etc).
 - When specifying a return value use `@returns` instead of `@return`. If there is no return value do not include one in the doc.
 
+- Avoid descriptions that don't add any additional information. Method descriptions should only be added when it's behavior is unclear.
+- Do not use block tags other than `@param` and `@returns` (e.g. `@memberof`, `@constructor`, etc).
+- Do not document default parameters. They are already documented by adding them to a declared function's arguments.
+- Do not use record types e.g. `{Object.<string, number>}`.
+- Do not create `@typedef` to use in JSDocs.
+- Do not use type unions e.g. `{(number|boolean)}`.
