 This cop checks the usage of pre-2.1 `Hash[args]` method of converting enumerables and
 sequences of values to hashes.
 
+Correction code from splat argument (`Hash[*ary]`) is not simply determined. For example,
+`Hash[*ary]` can be replaced with `ary.each_slice(2).to_h` but it will be complicated.
+So, `AllowSplatArgument` option is true by default to allow splat argument for simple code.

+This cop checks for the use of logical operators in an `unless` condition.
+It discourages such code, as the condition becomes more difficult
+to read and understand.
+
+This cop supports two styles:
+- `forbid_mixed_logical_operators` (default)
+- `forbid_logical_operators`
+
+`forbid_mixed_logical_operators` style forbids the use of more than one type
+of logical operators. This makes the `unless` condition easier to read
+because either all conditions need to be met or any condition need to be met
+in order for the expression to be truthy or falsey.
+
+`forbid_logical_operators` style forbids any use of logical operator.
+This makes it even more easy to read the `unless` condition as
+there is only one condition in the expression.
