+By default, when ClearML is integrated into your script, it automatically captures information from supported frameworks, 
+and parameters from supported argument parsers. But, you may want to have more control over what your experiment logs.
 
+### Frameworks
 To control a task's framework logging, use the `auto_connect_frameworks` parameter of [`Task.init()`](../references/sdk/task.md#taskinit). 
 Completely disable all automatic logging by setting the parameter to `False`. For finer grained control of logged 
 frameworks, input a dictionary, with framework-boolean pairs.

+### Argument Parsers
+To control a task's logging of parameters from argument parsers, use the `auto_connect_arg_parser` parameter of [`Task.init()`](../references/sdk/task.md#taskinit). 
+Completely disable all automatic logging by setting the parameter to `False` (this includes disabling logging of `LightningCLI` parameters). 
+
+```python
+auto_connect_arg_parser=False
+```
+
+For finer grained control of logged parameters, input a dictionary with parameter-boolean pairs. The `False` value 
+excludes the specified parameter. Unspecified parameters default to `True`.
+
+For example, the following code will not log the `Example_1` parameter, but will log all other arguments.
+
+```python
+auto_connect_arg_parser={"Example_1": False}
+```
+
+To exclude all unspecified parameters, set the `*` key to `False`. For example, the following code will log **only** the 
+`Example_2` parameter.
+
+```python
+auto_connect_arg_parser={"Example_2": True, "*": False}
+```

 ## Manual Logging
 To augment its automatic logging, ClearML also provides an explicit logging interface.
