+#### utterances Comments
+
+To use utterances you will need to [install the app](https://github.com/apps/utterances) to your GitHub repository by adding the following to `_config.yml`:
+
+```yaml
+repository: # GitHub username/repo-name e.g. "mmistakes/minimal-mistakes"
+```
+
+**Note:** Make sure the repo is public, otherwise your readers will not be able to view the issues/comments. The [issues feature](https://guides.github.com/features/issues/) also needs to be active on your repo.
+{: .notice--warning}
+
+To enable utterances on the front end set `comments.provider` and the color theme of the widget. 
+
+```yaml
+comments:
+  provider: "utterances"
+  utterances:
+    theme: "github-light" # "github-dark"
+```
