Fess está basado en [OpenSearch](https://github.com/opensearch-project/OpenSearch), pero no se requiere conocimiento o experiencia en OpenSearch. Fess proporciona una GUI de administración fácil de usar para configurar el sistema a través de tu navegador.

## Como Começar

Existem duas maneiras de testar o Fess. A primeira é baixar e instalar você mesmo. A segunda é usar [Docker](https://www.docker.com/products/docker-engine).

### Baixar e Instalar/Executar

O Fess 15.3 já está disponível e pode ser baixado na [página de lançamentos](https://github.com/codelibs/fess/releases "download"). As opções de download incluem: deb, rpm, zip.

Os comandos a seguir mostram como usar o download em formato zip:
