您可以通过两种方式尝试 Fess。第一种是自行下载并安装，第二种是使用 [Docker](https://www.docker.com/products/docker-engine)。

### 下载并安装/运行

Fess 15.3 现已发布，可在 [发布页面](https://github.com/codelibs/fess/releases "download") 下载。提供三种下载形式：deb、rpm、zip。

以下命令展示了如何使用 zip 下载：

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

## はじめに

Fessを試す方法は2つあります。1つは自分でダウンロードしてインストールする方法、もう1つは[Docker](https://www.docker.com/products/docker-engine)を使用する方法です。

### ダウンロードおよびインストール/実行

Fess 15.3が利用可能で、[リリースページ](https://github.com/codelibs/fess/releases "download")からダウンロードできます。ダウンロードには、deb、rpm、zipの3つの形式があります。

以下のコマンドは、zipファイルを使用する例です：
