I would suggest adding the following to the documentation here: https://docs.cloudron.io/packages/languagetool/
If you want to use a volume to install and store ngrams there, after creating that volume[link to doc], mount it to the Language Tool application under the βStorageβ menu and set it as a "read and writing" volume.
Normally the volumes are reachable via /mnt/volumens/<volume-id> but once mounted to an application are reachable via /media/<volumen-id>, therefore the command you need to use for installing the ngrams will be as follows:
/app/pkg/install-ngrams.sh /media/<volume-id> en es
and the path under /app/data/env has to be like NGRAMS_DATASET_PATH=/media/<volume-id>
That may help some user like me with a more step-by-step guide
