+
+Træfɪk can be configured using a TOML file configuration, arguments, or both.
+By default, Træfɪk will try to find a `traefik.toml` in the following places:
+- `/etc/traefik/`
+- `$HOME/.traefik/`
+- `.` the working directory
+
+You can override this by setting a `configFile` argument:
+
+```bash
+$ traefik --configFile=foo/bar/myconfigfile.toml
+```
+
+Træfɪk uses the following precedence order. Each item takes precedence over the item below it:
+
+- arguments
+- configuration file
+- default
+
+It means that arguments overrides configuration file.
+Each argument is described in the help section:
+```bash
+$ traefik --help
