Get started

The shortest path from installing BAML to checking your first function.

Install the toolchain

Install the BAML CLI and editor support for your environment. The versioned CLI reference remains the canonical source for exact installation methods and supported environments.

Create a project

A normal BAML project contains a baml.toml file and a baml_src/ directory. Put your functions and types under that source directory so the ordinary toolchain can discover them.

my-project/
├── baml.toml
└── baml_src/
    └── main.baml

Check your work

Use the CLI to check the project before generating or running client code. Continue to the BAML CLI overview for the versioned command surface.
