-## Advanced usage
-
-In your applications folder `/home/dokku/app_name` create a file called `DOCKER_OPTIONS_RUN` (or `DOCKER_OPTIONS_BUILD` or `DOCKER_OPTIONS_DEPLOY`).
-
-Inside this file list one Docker option per line. For example:
-
-```shell
---link container_name:alias
--v /host/path:/container/path
--v /another/container/path
-```
-
-The above example will result in the following options being passed to Docker during `dokku run`:
-
-```shell
---link container_name:alias -v /host/path:/container/path -v /another/container/path
-```
-
-You may also include comments (lines beginning with a #) and blank lines in the DOCKER_OPTIONS file.
