 You have to create a JSON file that serves as a config. The JSON must contain a `configs` array. For every entry, you can specify a certain path that must be matched as well as a file extension. You can use the `*` symbol to use the config entry for any path or filename. Note that the path option only matches the requested path from the start. Thatswhy you have to start with a `/` and can use paths like `/files/static/css`. The `headers` array includes a key-value pair of the actual header rule. The headers are not parsed so double check your spelling and test your site.
 
-The created JSON config has to be mounted into the container via a volume into `/config/headerConfig.json`. When this file does not exist inside the container, the header middleware will not be active.
+The created JSON config has to be mounted into the container via a volume into `/config/headerConfig.json` per default. When this file does not exist inside the container, the header middleware will not be active.
 
 Example command to add to the docker run command:
 
 ```
--v /your/path/to/the/config/myConfig.json:/config/headerConfig.json
+docker run ... -v /your/path/to/the/config/myConfig.json:/config/headerConfig.json
+```
+
+You can also specify where you want to mount your config into with the `header-config-path` flag:
+
+```
+docker run ... -v /your/path/to/the/config/myConfig.json:/other/path/myConfig.json -header-config-path=/other/path/myConfig.json
 ```
 
 On startup, the container will log the found header rules.
