 `Recase` helps you to convert a string from any case to any case.
 
 
+## Why?
+
+One can ask: "Why should I use `recase` when I can use built-in `Macro` module?". But, you have to keep in mind that `Macro`'s functions are [not suitable](https://github.com/elixir-lang/elixir/blob/4aa81645b0588b56fb61cd154dcaee354732aa5c/lib/elixir/lib/macro.ex#L1265) for general case usage:
+
+> Do not use it as a general mechanism for underscoring or camelizing strings as it does not support Unicode or characters that are not valid in Elixir identifiers.

 ### Upper
 
-```elixir
-Recase.to_upper("some-value")
-# => "SomeValue"
+Upper (or Pascal) case uses mixed case with lower and upper cased characters. Separates words from each other with the upper case letters. Starts with upper case letter.
 
-Recase.to_upper("Some value")
-# => "SomeValue"
+```elixir
+Recase.to_upper("some-value") # => "SomeValue"
+Recase.to_upper("Some value") # => "SomeValue"
 ```
 
 ### Camel
 
-```elixir
-Recase.to_camel("some-value")
-# => "someValue"
+Camel case uses mixed case with lower and upper cased characters. Separates words from each other with the upper cased letters. Starts with lower case letter.
 
-Recase.to_camel("Some Value")
-# => "someValue"
+```elixir
+Recase.to_camel("some-value") # => "someValue"
+Recase.to_camel("Some Value") # => "someValue"
 ```
 
 ### Snake
 
-```elixir
-Recase.to_snake("someValue")
-# => "some_value"
+Snake cases uses all lower case. Uses `_` as a separator.
 
-Recase.to_snake("Some Value")
-# => "some_value"
+```elixir
+Recase.to_snake("someValue") # => "some_value"
+Recase.to_snake("Some Value") # => "some_value"
 ```
 
 ### Kebab
 
+Kebab cases uses all lower case. Uses `-` as a separator.
+
+```elixir
+Recase.to_kebab("someValue") # => "some-value"
+Recase.to_kebab("Some Value") # => "some-value"
+```
+
+### Constant
+
+Constant case uses all upper case. Uses `_` as a separator.
+
 ```elixir
-Recase.to_kebab("someValue")
-# => "some-value"
+Recase.to_constant("SomeValue") # => "SOME_VALUE"
+Recase.to_constant("some value") # => "SOME_VALUE"
+```
+
+### Dot
 
-Recase.to_kebab("Some Value")
-# => "some-value"
+Dot case uses all lower case similar to snake case. Uses `.` as a separator.
+
+```elixir
+Recase.to_dot("SomeValue") # => "some.value"
+Recase.to_dot("some value") # => "some.value"
 ```
 
+### Path
+
+Path case preserves case, you can also provide a separator as the second argument.
+
+```elixir
+Recase.to_path("SomeValue") # => "Some/Value"
+Recase.to_path("some value", "\\") # => "some\\value"
+```
