What is astro-lilypond?

This project is an integration for Astro, a tool for building websites, that lets a site render LilyPond music notation as images. LilyPond itself is a separate program that turns written instructions into typeset sheet music, similar to how a markup language turns text into a formatted document. This integration connects that music notation system to an Astro website so notation can appear as an image directly on a page. According to the README, there are two ways to add music notation to a page: writing it directly inside a Markdown file, or using a LilyPond component placed in a page's code. It also states that the integration works with both of Astro's supported Markdown processors, named unified and satteri, so it should fit into an existing Astro project without requiring a switch in how Markdown is handled. Another stated feature is that it adds zero runtime JavaScript, meaning the notation images do not require extra JavaScript code to load or display in a visitor's browser once the page is built. The README also says it supports all LilyPond syntax, though it does not go into further detail about what that syntax includes or how complex compositions are handled. The repository is organized into two main folders. One, named package, holds the actual code that gets published as the astro-lilypond package for other developers to install. The other, named docs, holds a documentation website built with Starlight, a documentation site generator, and that site is deployed publicly. The README itself is quite short and mostly describes what the integration does at a high level rather than explaining installation steps or configuration options in this top-level file. Anyone wanting deeper setup instructions is pointed to the separate hosted documentation site rather than finding those details directly in the README.
