 > For security reasons, we strongly recommend providing a project API key via the `--key` option in automations or CI environments (GitHub Actions, CircleCI, Travis CI, etc.). It's also recommended if you're working with multiple ReadMe projects to avoid accidentally overwriting existing data.
 
+You can also pass in your API key via the `RDME_API_KEY` environmental variable. Here is the order of precedence when passing your API key into `rdme`:

+1. The `RDME_API_KEY` environmental variable. If that isn't present, we look for...
+1. The API key value stored in your local configuration file (i.e., the one set via `rdme login`)
+
 `rdme whoami` is also available to you to determine who is logged in, and to what project. You can clear your stored credentials with `rdme logout`.
