+Run output directory can contain override parameters for the job:
 
-### Configuring hydra.job.override_dirname
-`hydra.job.override_dirname` can be configured via hydra.job.config.override_dirname.
-You can exclude keys such as `random_seed` or change the separator used to construct override_dirname.
+See [Override dirname](./job#hydrajoboverride_dirname) in the Job configuration page for details on how to customize
+`hydra.job.override_dirname`.
 
 ```yaml
 hydra:
-  job:
-    config:
-      # configuration for the ${hydra.job.override_dirname} runtime variable
-      override_dirname:
-        kv_sep: '='
-        item_sep: ','
-        exclude_keys: []

-### Customizing outputs with substitution through the CLI 
-
-Outputs can also be configured through the CLI, like any other configuration.
-
->python train.py model.nb_layers=3 hydra.run.dir=3_layers
-
-This feature can become really powerful to write multiruns without boilerplate using interpolation.
-
-```
-python train.py --multirun \ 
-    model.nb_layers=1,2,3,5 \
-    hydra.sweep.dir=multiruns/layers_effect \ 
-    hydra.sweep.subdir=\${model.nb_layers}
+  run:
+    dir: output/${hydra.job.override_dirname}
 ```

-With bash, be careful to escape the $ symbol. Otherwise, bash will try to resolve the interpolation, instead of passing it to Hydra.
