lerna support in serverless jetpack

I read that lerna is supported in serverless jetpack.

My project structure looks like the following:

```

--root

----shared-modules

------------packageD

-----------------serverless.yml

-----------------package.json

----packageA

--------serverless.yml

--------package.json

----packageB

--------serverless.yml

--------package.json

----packageC

--------serverless.yml

--------package.json

```

**Requirement:**

PackageA depends on sharedModules/packageD and packageB

packageB depends on packageC

packageC depends on sharedModules

I am using npm. What configurations do I need to make in serverless-jetpack for this exactly? I see it is supported but not clear on what needs to be done to achieve this.
