[Question] typescript path mapping

I am just getting started with ts-morph and think that my typescript [path mappings](https://www.typescriptlang.org/docs/handbook/module-resolution.html#path-mapping) are not working for some reason.

Should this work out of the box, or do we need a [custom module mapping](https://ts-morph.com/setup/index#custom-module-resolution)?
If so, are there any examples available?

Start with the TypeScript path mapping documentation and ts-morph's custom module resolution guide, both linked in the issue. Verify whether path mappings work with the default setup or require custom mapping, then document a minimal example and the expected configuration.
