+title: Python Fire
+---
+
+Python Fire is a Python package for creating command-line interfaces. 
+ClearML integrates seamlessly with `fire` and automatically logs its command-line parameters.
+
+All you have to do is add two lines of code:
+
+```python
+from clearml import Task
+task = Task.init(task_name="<task_name>", project_name="<project_name>")
+```
+
+When the code runs, ClearML logs your command-line arguments, which you can view in the [WebApp](../webapp/webapp_overview.md), in the experiment's 
+**Configuration > Hyperparameters > Args** section. 
+
+![Fire integration](../img/integrations_fire_params.png)
+
+In the UI, you can clone the task multiple times and set the clones' parameter values for execution by the [ClearML Agent](../clearml_agent.md).
+When the clone is executed, the executing agent will use the new parameter values as if set by the command-line.
+
+See [code examples](https://github.com/allegroai/clearml/blob/master/examples/frameworks/fire) demonstrating integrating
+ClearML with code that uses `fire`.
