-1. Add a `.env` file to *each* folder with the following key/value pairs:
-
-- `CHRONOS_DB` = `MongoDB` or `PostgreSQL` 
-- `CHRONOS_URI` = The URI to the desired MongoDB or PostgreSQL database to save health metrics via **Chronos**
-- `BOOK_URI`= A **MongoDB** URI for the bookserver microservice to use

 2.  Verify that @chronosmicro/tracker is a dependency in each of the /books, /customers, /frontend, and /orders folders (see the `package.json` in each folder).
 
 - If the @chronosmicro/tracker dependency is listed as a remote npm package (i.e. `"@chronosmicro/tracker": "^8.0.3"`) and you've ran *npm install*, no further work is needed continue to step 3. If you have the dependency as `"@chronosmicro/tracker": "file:./chronos_npm_package"`, make sure to change the version from `"file:./chronos_npm_package"` to `"^8.0.3"` and run npm install.
