{
  "name": "Jekyll Website Dev Container",
  "image": "mcr.microsoft.com/devcontainers/jekyll",
  "customizations": {
    "vscode": {
      "settings": {
        "editor.tabSize": 2
      },
      "extensions": [
        "shopify.ruby-lsp",
        "davidanson.vscode-markdownlint"
      ]
    }
  }
}
