@harshsoni7 Glow seems like a plug-and-play kind of thing. You install it and render markdowns on your terminal. It doesn't seem to provide any functions to integrate it with an existing go CLI. There isn't any documentation as such on https://pkg.go.dev/github.com/charmbracelet/glow#section-documentation

Correct me if I am wrong here. However, I see another package by the same vendor named lipgloss that does CLI output styling. https://pkg.go.dev/github.com/charmbracelet/lipgloss
