+### Examples
+
+If you want that Træfik uses Consul tags correctly you need to defined them like that:
+```json
+traefik.enable=true
+traefik.tags=api
+traefik.tags=external
+```
+
+If the prefix defined in Træfik configuration is `bla`, tags need to be defined like that:
+```json
+bla.enable=true
+bla.tags=api
+bla.tags=external
+```
