 The KittyCAD modeling app uses TOML files for configuration:
 
-* **User Settings**: `user.toml` - See [complete documentation](/docs/kcl/settings/user.toml)
-* **Project Settings**: `project.toml` - See [complete documentation](/docs/kcl/settings/project.toml)
+* **User Settings**: `user.toml` - See [complete documentation](/docs/kcl/settings/user)
+* **Project Settings**: `project.toml` - See [complete documentation](/docs/kcl/settings/project)
