Setting up an Amazon S3 bucket to share files

1. Sign into your AWS console: https://console.aws.amazon.com/console/home
2. Click on “S3”.
3. Click “Create Bucket” and enter a Bucket Name using only alphanumeric characters and no spaces. We recommend prefixing it with your organization’s name, so something like “myorganization-downloads” works well. No other customization is necessary, so then click “Create” to complete the creation process.
4. Choose the bucket you just created from the list of buckets to navigate into it.
5. Once inside the folder, click “Upload” and upload all the files you want there.
6. After your files are done uploading, select them by clicking the square to their left and then choose “Actions” -> “Make Public”. This will make the files publicly accessible.
7. To get the public URL of a file, select the file and then click the Properties tab (in the top right of the window). The Link attribute contains the publicly accessible URL of the file.

[공통] 마크다운 markdown 작성법

1. 마크다운에 관하여

1.1. 마크다운이란?

**Markdown**은 텍스트 기반의 마크업언어로 2004년 존그루버에 의해 만들어졌으며 쉽게 쓰고 읽을 수 있으며 HTML로 변환이 가능하다. 특수기호와 문자를 이용한 매우 간단한 구조의 문법을 사용하여 웹에서도 보다 빠르게 컨텐츠를 작성하고 보다 직관적으로 인식할 수 있다. 마크다운이 최근 각광받기 시작한 이유는 깃헙(https://github.com) 덕분이다. 깃헙의 저장소Repository에 관한 정보를 기록하는 README.md는 깃헙을 사용하는 사람이라면 누구나 가장 먼저 접하게 되는 마크다운 문서였다. 마크다운을 통해서 설치방법, 소스코드 설명, 이슈 등을 간단하게 기록하고 가독성을 높일 수 있다는 강점이 부각되면서 점점 여러 곳으로 퍼져가게 된다.
