The timeout-method section recommends the deprecated --timeout_method spelling. Use --timeout-method, matching the plugin help, while keeping the timeout_method configuration key and historical changelog unchanged.

Validated the installed plugin help, ran an external smoke test with each CLI spelling, rendered the README as HTML, and ran git diff --check.

Related README detail that may be useful to include here, rather than opening a parallel documentation PR:

On current main (a42e4c5), the Debugger Detection paragraph advertises --disable-debugger-detection, but the registered option is --timeout-disable-debugger-detection. A possible replacement is:

This functionality can be disabled with the
``--timeout-disable-debugger-detection`` flag or the
``timeout_disable_debugger_detection`` ini setting.

This also removes the environment-variable claim: get_env_settings reads this setting from CLI/ini only; its environment-variable lookup is for PYTEST_TIMEOUT.

Verified against that actual HEAD with plugin auto-loading disabled and explicit -p pytest_timeout: the documented flag is rejected with exit 4; the registered flag and -o timeout_disable_debugger_detection=true each run one passing configuration assertion that the setting is True. These are local, finite configuration checks, not the full timeout-behavior suite or remote CI.

Feel free to include this if it fits your scope. AI assistance was used for this check; no code-behavior change is proposed.
