+# Formatting codes
+
+When formatting a message you can use arguments in the form of `{{name}}`. Following arguments are available by default:
+
+| Name        | Description                                                                                                                                                           | Example               |
+| :---------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :-------------------- |
+| `message`   | Log message                                                                                                                                                           | `My message`          |
+| `level`     | Uppercase level name. Will have colors attached to it if the output is stdout or stderr                                                                               | `ERROR`               |
+| `timestamp` | UTC timestamp the log function was called (Technically the time the format function was called). Can be formatted using the `timestamp_format` field of the formatter | `2023-11-27 20:49:47` |
+| `path`      | Relative path to the caller of the log macro                                                                                                                          | `src\main.rs`         |
+
+Users can also specify custom arguments by either supplying a `Vec<(&str, String)>` of key-value pairs of the argument name and value or using the fields in the macros:
+
+```rust,ignore
+logging_rs::log!(logger, "My message with {{arg}}", "arg" = "my arguments")
+```
+
+## ASCII format characters
+
+Most terminals support special ASCII characters.
+
