ディレクトリとファイルの作成

YOUR_DIRRECYORYE/static/adminディレクトリを作成し、配下に2つのファイルを作成します。 index.htmlとconfig.ymlです。

index.html

<!doctype html>
<html>
<head>
  <meta charset="utf-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  <title>Content Manager</title>
</head>
<body>
  <!-- Include the script that builds the page and powers Netlify CMS -->
  <script src="https://unpkg.com/netlify-cms@^2.0.0/dist/netlify-cms.js"></script>
</body>
</html>

config.yml

backend:
      name: github
      branch: master # ブランチ名を記入します
      repo: yoshitaku-jp/challenge-every-month # 自分のリポジトリを記入します
    
    media_folder: "static/images/uploads" # YOUR_DIRRECYORYE/staticの配下に画像のアップロード先を指定します。
    public_folder: "/images/uploads" # The src attribute for uploaded media will begin with /images/uploads
    
    collections:

        create: true # Allow users to create new documents in this collection
        slug: "{{year}}-{{month}}-{{day}}-{{slug}}" # Filename template, e.g., YYYY-MM-DD-title.md
        fields: # The fields for each document, usually in front matter
