# Run first command

캐시 서버(arcus-memcached)가 구동된 상태라면, 아래와 같은 명령으로 캐시 서버에 연결하고 명령을 전송해 볼 수 있습니다.

```
telnet localhost 11211
```

캐시 서버에 연결되었다면, 아래와 같은 명령을 통해 데이터를 저장할 수 있습니다.

```
set sample-data 0 30 22
this is a sample data!
```

수행 결과로 `STORED` 응답을 받았다면, `sample-data`라는 key로 저장된 데이터를 조회할 수 있습니다.\
`set` 명령을 보낸 후 30초가 지나면 저장된 데이터가 사라지는 점에 유의하세요.\
만약 데이터가 만료되지 않기를 원하는 경우, `set` 명령의 세 번째 인자로 `30` 대신 `0`을 지정하면 됩니다.

```
get sample-data
```

```
VALUE sample-data 0 22
this is a sample data!
END
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://jam2in.gitbook.io/arcus-documentation/get-started/run-first-command.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
