# Linux Kernel Module Cheat

#### 38.5.1. Documentation verification

When running build-doc, we do the following checks:

- `<<>>` inner links are not broken

- `link:somefile[]` links point to paths that exist via asciidoctor/extract-link-targets. Upstream wontfix at: https://github.com/asciidoctor/asciidoctor/issues/3210

- all links in non-README files to README IDs exist via `git grep` + asciidoctor/extract-header-ids

The scripts prints what you have to fix and exits with an error status if there are any errors.
