 The images are ready to run with limited functionality.
 At container startup, the startup.py wrapper (from the dockerdata directory linked above) checks for `PDNS_RECURSOR_API_KEY` / `PDNS_AUTH_API_KEY` / `DNSDIST_API_KEY` environment variables for the product you are running.
-If such a variable is found, `/etc/powerdns-api.conf` or `/etc/dnsdist-api.conf` is written, enabling the webserver in all products, and the dnsdist console.
+If such a variable is found, `/etc/powerdns/recursor.d/_api.conf` / `/etc/powerdns/pdns.d/_api.conf` / `/etc/dnsdist/conf.d/_api.conf` is written, enabling the webserver in all products, and the dnsdist console.
 For the dnsdist console, make sure that your API key is in a format suitable for the console (use `makeKey()`).
 
 The default configs shipped in the image (see dockerdata above) parse all files in `/etc/powerdns/pdns.d` / `/etc/powerdns/recursor.d` / `/etc/dnsdist/conf.d`.
-The image also ships a symlink to the API config file inside those `.d` dirs.
 For Auth and Recursor, extra configuration can be passed on the command line, or via a volume mount into `/etc/powerdns` or the `.d` dir.
 For dnsdist, only the volume mount is applicable.
 
-If you want to volume mount a config, but also take the keys from the environment, please take care to include the same `X-api.conf` symlink in your `.d` directory.
+If you want to volume mount a config, but also take the keys from the environment, please take care to include the same `_api.conf` file in your `.d` directory.

+If you want to read the configuration for debugging purposes, you can run the containers with the `DEBUG_CONFIG` environment variable set to `'yes'`.
+This will print the full config on startup. Please keep in mind that this also includes credentials, therefore this setting should never be used in production environments.
