Frequently Asked Questions
What is TOML?
TOML (Tom's Obvious Minimal Language) is a configuration file format designed to be easy to read. It's used by Rust (Cargo.toml), Python (pyproject.toml), and Hugo (config.toml).
What are [[double brackets]] in TOML?
[[double brackets]] define an array of tables — equivalent to an array of objects in JSON. Each [[section]] adds a new object to the array.
