Instructions on running tests

Subject of the issue

I’ve got an idea, for a contribution I’d like to make. My first port of call was to try and run the tests “out of the box”.

A fresh yarn install && yarn test outputs:

yarn run v1.5.1
$ remark . -qf && eslint . && lerna run test

/Users/jonsherrard/playground/mdx/packages/runtime/src/index.js
  4:22  error  Unable to resolve path to module '@mdx-js/tag'  import/no-unresolved

✖ 1 problem (1 error, 0 warnings)

error An unexpected error occurred: "Command failed.
Exit code: 1
Command: sh
Arguments: -c remark . -qf && eslint . && lerna run test
Directory: /Users/jonsherrard/playground/mdx
Output:
".

I’ve tried a few combinitions of lernna link in various packages, to no avail.
