It's a great way to add comments to your blog. All I need to do is install the app to my repo and enable disuccsion. Users need to sign in with GitHub to comment. Perfect choice for tech blogs/documentation. One of my favorite documentation tools Astro Starlight also has a [starlight-giscus plugin](https://github.com/dragomano/starlight-giscus). I am using it on https://docs.kunkun.sh/
