The following commands show how to use the zip download:

    $ unzip fess-15.3.x.zip
    $ cd fess-15.3.x
    $ ./bin/fess

For more details, see the [Installation Guide](https://fess.codelibs.org/15.3/install/index.html).

### Docker

We provide Docker images on [ghcr.io](https://github.com/orgs/codelibs/packages). We also provide a Docker Compose (YAML) file in [this repository](https://github.com/codelibs/docker-fess/tree/master/compose). 

  -H "Content-Type: application/x-ndjson" \
  -u admin:admin \
  --data-binary @fess-documents.json
```

#### Index Settings Migration

Fess uses OpenSearch/Elasticsearch internally, so you can:

1. Export index mappings and settings from source
2. Apply custom analyzers in Fess's `fess_config.properties`
3. Create synonym dictionaries in Fess's dictionary directory
