 Multiple configuration files can be specified and used by the bot or the bot can read its configuration parameters from the process standard input stream.
 
+You can specify additional configuration files in `add_config_files`. Files specified in this parameter will be loaded and merged with the initial config file. The files are resolved relative to the initial configuration file.
+This is similar to using multiple `--config` parameters, but simpler in usage as you don't have to specify all files for all commands.
+
 !!! Tip "Use multiple configuration files to keep secrets secret"
     You can use a 2nd configuration file containing your secrets. That way you can share your "primary" configuration file, while still keeping your API keys for yourself.
 
+    ``` json title="user_data/config.json"
+    "add_config_files": [
+        "config-private.json"
+    ]
+    ```
+    
+    ``` bash
+    freqtrade trade --config user_data/config.json <...>
+    ```
+
+    The 2nd file should only specify what you intend to override.
+    If a key is in more than one of the configurations, then the "last specified configuration" wins (in the above example, `config-private.json`).
+
+    For one-off commands, you can also use the below syntax by specifying multiple "--config" parameters.
+
     ``` bash
     freqtrade trade --config user_data/config.json --config user_data/config-private.json <...>
     ```
-    The 2nd file should only specify what you intend to override.
-    If a key is in more than one of the configurations, then the "last specified configuration" wins (in the above example, `config-private.json`).
+
+    This is equivalent to the example above - but `config-private.json` is specified as cli argument.
