How to test

1. Change "bolt": "git://github.com/flow-typed/bolt.git#master" in package.json to
   "bolt": "git://github.com/goodmind/bolt.git#master" or merge Add flow version based symlink resolution bolt#2
2. yarn
3. Setup https://verdaccio.org/ and run NPM server verdaccio
4. yarn sync-definitions
5. ./node_modules/bolt/bin.js, this command would link packages with dependencies, but given that current definitions doesn't have them you would need to add some
6. ./node_modules/bolt/bin.js publish --registry http://localhost:4873 (NOTE: make sure that it isn't real npm registry, I would even log out from npm first, so you wouldn't accidentally publish packages)
7. Test installing types with yarn add @flowtyped/whatever --registry http://localhost:4873
