Note
giscus is still under active development. GitHub is also still actively developing Discussions and its API. Thus, some features of giscus may break or change over time.

How it works

When giscus loads, the GitHub Discussions search API is used to find the Discussion associated with the page based on a chosen mapping (URL, pathname, <title>, etc.). If a matching discussion cannot be found, the giscus bot will automatically create a discussion the first time someone leaves a comment or reaction.

To comment, visitors must authorize the giscus app to post on their behalf using the GitHub OAuth flow. Alternatively, visitors can comment on the GitHub Discussion directly. You can moderate the comments on GitHub.
