+Træfɪk can hot-reload those rules which could be provided by [multiple configuration backends](/toml/#configuration-backends).
 
-The dynamic configuration concern route rules which could be provided by [multiple configuration backends](/toml/#configuration-backends).
 We only need to enable `watch` option to make Træfɪk watch configuration backend changes and generate its configuration automatically.
 Routes to services will be created and updated instantly at any changes.
