-- categories used by `Pull Request Summary` in the
-  [PR Template](https://github.com/cataclysmbnteam/Cataclysm-BN/blob/upload/.github/pull_request_template.md).
-- these are only guidelines, not rules. choose the best category for your PR freely.

+- `Json` reorganizations
+- `docs/`, `.github/` and repository changes

+Improve build process:

+- `ci`: Changes to CI process
+- `chore`: Other changes that don't fit into any of the above categories
+- `revert`: Reverts a previous commit
+
+## Scopes
