-### Serve `npm`
-
-We've included a simple npm registry mock which allows you to do an `npm install @capire/<package>` locally. Use it as follows:
-
-1. Start the @capire registry:
-```sh
-npm run registry
-```
-> While running this will have `@capire:registry=http://localhost:4444` set with npmrc.
-
-2. Install one of the @capire packages wherever you like, e.g.:
-```sh
-npm add @capire/common @capire/bookshop
