 1. Creating a symbolic link in the chart directory to the external file, or
 2. using `--set-file` to specify the contents of the file. E.g:
-   `helm upgrade --install galaxy cloudve/galaxy -n galaxy --set-file extraFileMappings."/galaxy/server/static/welcome\.html".content=/home/user/data/welcome.html`
+   `helm upgrade --install galaxy cloudve/galaxy -n galaxy --set-file extraFileMappings."/galaxy/server/static/welcome\.html".content=/home/user/data/welcome.html --set extraFileMappings."/galaxy/server/static/welcome\.html".applyToWeb=true`
+
+Alternatively, if too many `.applyTo` need to be set, the apply flags can be inserted instead to the `extraFileMappings` (in addition to the --set-file in the cli) for that file in your `values.yaml`, with no `content:` part (as that is done through the `--set-file`):
