 ## Backend
 
 1. Generate a self-signed certificate and key for localhost and configure your system to trust it. The application ["mkcert"](https://github.com/FiloSottile/mkcert) is a helpful tool to accomplish this.
-1. Update `backend.baseUrl` in app-config.local.yaml to use an `https:` address, and copy the contents of the certificate and key files into `backend.https.certificate.cert` and `backend.https.certificate.cert`, respectively. Your app-config.local.yaml should look something like:
+1. Update `backend.baseUrl` in app-config.local.yaml to use an `https:` address.
+1. Add the certificate and key to `backend.https.certificate.cert` and `backend.https.certificate.cert`, respectively.
    ```yaml
    backend:
      baseUrl: https://localhost:7007
      https:
        certificate:
+         # You may copy the contents of the file...
          cert: |
            -----BEGIN CERTIFICATE-----
            MIIDCTCCAfGgAwIBAgIUZ9VhZckcy690L
            ...
            -----END CERTIFICATE-----
-         key: |
-           -----BEGIN PRIVATE KEY-----
-           MIIEvAIBADANBgkqhkiG9w0BAQ

-           -----END PRIVATE KEY-----
+         # ... or use a path
+         key:
+           $file: ./certs/localhost-key.pem
    ```
 1. Start the backend with `NODE_EXTRA_CA_CERTS=/absolute/path/to/cert.pem yarn start-backend`
 
 ## Frontend
 
-Webpack will generate a self signed certificate automatically in development environments when the protocol in the `baseUrl` is `https`. Therefore, simply add this to your local config:
+1. As with the backend instructions above, a trusted certificate and key are needed.
+1. Update `app.baseUrl` and `backend.cors.origin` in app-config.local.yaml to use an `https:` address.
+1. Add the certificate and key to `app.https.certificate.cert` and `app.https.certificate.cert`, respectively.
 
-```yaml
-app:
-  baseUrl: https://localhost:3000
-backend:
-  cors:
-    origin: https://localhost:3000
-```
+   ```yaml
+   app:
+     baseUrl: https://localhost:3000
+     https:
+       certificate:
+         cert:
+           $file: ./certs/localhost.pem
+         key:
+           $file: ./certs/localhost-key.pem
+   backend:
+     cors:
+       origin: https://localhost:3000
+   ```
 
-and start the app with `yarn start`. As with the backend instructions above, the certificate must be trusted.
+1. and start the app with `yarn start`.
 
 Depending on what plugins are in use, you may need to override additional URLs to use `https` for those endpoints to work.
