   * `timeout` timeout in [zeit/ms](https://www.npmjs.com/package/ms) format. (e.g. `"2000ms"`, `20s`, `1m`). Default `10s`.
   * `httpHeaders` to apply URL specific headers, see example below.
   * `ignorePatterns` an array of objects holding regular expressions which a link is checked against and skipped for checking in case of a match. Example: `[{ pattern: /foo/ }]`
-  * `replacementPatterns` an array of objects holding regular expressions which are replaced in a link with their corresponding replacement string. This behavior allows (for example) to adapt to certain platform conventions hosting the Markdown. The special replacement `{{BASEURL}}` can be used to dynamically link to the base folder (used from `projectBaseUrl`) (for example that `/` points to the root of your local repository). Example: `[{ pattern: /^.attachments/, replacement: "file://some/conventional/folder/.attachments" }, { pattern: ^/, replacement: "{{BASEURL}}/"}]`

You can add `"global": true` to use a global regular expression to replace all instances.
   * `projectBaseUrl` the URL to use for `{{BASEURL}}` replacement
   * `ignoreDisable` if this is `true` then disable comments are ignored.
   * `retryOn429` if this is `true` then retry request when response is an HTTP code 429 after the duration indicated by `retry-after` header.
