Missing documentation for the configuration file

[andreasciamanna]

The Configuration section of the README.md file, says:

Configuration

You can configure standard-version either by:

1. Placing a standard-version stanza in your package.json (assuming
   your project is JavaScript).
2. Creating a .versionrc, .versionrc.json or .versionrc.js.

• If you are using a .versionrc.js your default export must be a configuration object, or a function returning a configuration object.

Any of the command line parameters accepted by standard-version can instead
be provided via configuration. Please refer to the conventional-changelog-config-spec for details on available configuration options.

conventional-changelog-config-spec has little to do with the configuration file of standard-version.

As far as I can see, there is no detailed documentation of the file, only some generic mentions that "Any of the command line parameters accepted by standard-version can instead be provided via configuration" (without saying how) and some specific configurations such as the bumpFiles.

If I want to skip tags, for instance, I need to figure out how by myself (which I did, looking at the source code or reading unrelated issues that were sharing their configuration file).

Maybe I'm just missing the place where this is documented?
