Filesystem→
Pull data stored in markdown, JSON, YAML, and other files. Grab only the data you need without importing a whole file, or query for metadata associated with multiple files.
Headless CMSs→
With integrations with dozens of CMSs like Contentful, WordPress and Drupal, teams can produce content in the system of their choice, then easily pull it into Gatsby.
