+
+Simple utility written in `go` that extends the standard `fmt.Sprintf` and `fmt.Printf` functions. It allows you to set foreground/background color, **bold**, <u>underlined</u> and _italic_ text.
+
+
+
+----
+
+## (1) Format
+
+
+
+##### Base format
+
+```go
+${<target text>}(<fg>:<bg>)
+```
+
+- `<target text>` is the text that will be colorized.
+- `<fg>` is the name of the foreground color (*c.f. [color list](https://git.xdrm.io/go/clifmt/src/master/colors.go#L15)*), or an hex color (*e.g.`#00ffaa`, `#0fa`*).
+- `<bg>` is the name of the background color with the same syntax as for the foreground.
+
+> Note that it is not recommended to nest the different coloring formats.
+
+
+
+##### Foreground only
+
+```go
+${<target text>}(<fg>)
+```
+
+- `<target text>` is the text that will be colorized.
+- `<fg>` is the name of the foreground color.
+
+
+
+##### Background only
+
+```go
+${<target text>}(:<bg>)
+```
+
+- `<target text>` is the text that will be colorized.
+- `<bg>` is the name of the background color.
