# Data `coltrane` is designed to be used without a database, however, sometimes it's useful to have access to data inside your templates. ## JSON data directory Create a directory named `data` in your project folder (if it doesn't already exist) and add JSON files. The name of the file (without the `json` extension) will be used as the key in the context data. If there are JSON files in sub-directories, the directory names will be included in the dictionary hierarchy. **`data/author.json`** ```JSON { {"name": "Douglas Adams"} } ``` **`data/books/book.json`** ```JSON { {"title": "The Hitchhiker's Guide to the Galaxy"} } ``` **`content/index.md`** ```markdown # index {{ data.author.name }} is the author. {{ data.books.book.title }} is the book title. ``` **Generated `index.html`** ```html
