# Python Edition Rule Book The Python edition is scoped to Windows to Linux migration. It ships two rule sources: - `rules/migration_rules.json`: the MC runtime rule pack used by the Findings tab and MC auto-fixes. - `rules/Migrate_Studio_Rules.xlsx`: the editable workbook rule book used by the standard Rules tab and contextual fixers. Rules in this edition are tested against synthetic `STUDY001` fixtures. Add new examples there when adding or changing a rule.
