# Usage

The Server is running on port 8010, this port should exposed.

    $ docker pull silviof/docker-languagetool
    [...]
    $ docker run --rm -p 8010:8010 silviof/docker-languagetool

Or you run it in background via `-d`-option.


## ngram support

To support [ngrams] you need an additional volume or directory mounted to the
`/ngrams` directory. For that add a `-v` to the `docker run`-command.

    docker run ... -v /path/to/ngrams:/ngrams ...

Download English ngrams with the commands:

    mkdir ngrams
    wget https://languagetool.org/download/ngram-data/ngrams-en-20150817.zip
    (cd ngrams && unzip ../ngrams-en-20150817.zip)
    rm -f ngrams-en-20150817.zip


One can use them using web browser plugin "Local server (localhost)" setting by running:

    docker run -d --name languagetool -p 127.0.0.1:8081:8010 -v `pwd`/ngrams:/ngrams:ro --restart=unless-stopped silviof/docker-languagetool
