 The **first** time you work with this package, you must build **all** packages within the monorepo. This is because packages that depend on other packages located inside this monorepo are symlinked when run from **within** the monorepo. This allows you to make changes across multiple packages without first publishing dependent packages to NPM. To build all packages, run the following from the monorepo root directory:
 
 ```bash
-yarn lerna:rebuild
+PKG=0x.js yarn build
 ```
 
 Note: If you move this package out of the monorepo, it will work without this step. Make sure you copy it out on the `master` branch since the `development` version might rely on not-yet published changes to other packages.
