+# title: Prettier
+# homepage: https://prettier.io/
+# tagline: Prettier is an opinionated code formatter.
+# description: |
+#   The core value of Prettier is not in what it gives, but in what it takes away: countless hours of bikeshedding over code style choices. Also, it makes git merges much nicer.
+# examples: |
+#   Prettify all web files in a project, recursively:
+#   
+#   ```bash
+#   prettier --write '**/*{.md,.js,.html,.css}' --ignore ./dist
+#   ```
+#   
+#   Tell Prettier which files to ignore every time
+#   
+#   ```bash
+#   echo "./dist" >> .prettierignore
+#   ```
+#   
+#   Tell Prettier which settings to use - do NOT use `package.json` when it's not necessary!
+#   
+#   **`.prettierrc`**:
+#   
+#   ```bash
+#   {
+#     "trailingComma": "none",
+#     "tabWidth": 2,
+#     "singleQuote": true,
+#     "proseWrap": "always"
+#   }
+#   ```
