## Documentation Generator

Configuration related to the behavior of the Forge documentation generator. These keys are set in `[doc]` section.

##### `out`

* Type: string
* Default: `docs`
* Environment: `FOUNDRY_DOC_OUT`

An output path for generated documentation.

##### `title`

* Type: string
* Default: `""`
* Environment: `FOUNDRY_DOC_TITLE`

Title for the generated documentation.

##### `book`

* Type: string
* Default: `book.toml`
* Environment: `FOUNDRY_DOC_BOOK`

Legacy configuration key retained for compatibility. `forge doc` now generates a Vocs site and does not read `book.toml`.

##### `homepage`

* Type: string
* Default: `README.md`
* Environment: `FOUNDRY_DOC_HOMEPAGE`

* Default: current Git revision
* Environment: `FOUNDRY_DOC_COMMIT`

The Git commit hash, tag, or branch used for source and homepage links.

##### `path`

Legacy configuration key retained for compatibility. Source links are now derived from the project root and source file path.

* Default: `[]`
* Environment: `FOUNDRY_DOC_IGNORE`

List of files to ignore when generating documentation. This is a comma separated list of glob patterns.
