# System Configuration File

## System Configuration File

{% hint style="info" %}
Since **magento-scripts 1.5.1**
{% endhint %}

This configuration file is located in your home directory and should have a name `.cmarc`.\
As it is not created automatically, you will need to do it manually.\
The default configuration file looks like this:

{% code title="$HOME/.cmarc" %}

```javascript
  {
    "useNonOverlappingPorts": false,
    "analytics": true
  }
```

{% endcode %}

This configuration file contains the following configuration options:

### Use Non-Overlapping Ports

{% hint style="info" %}
Recommended to enable this option if you are working with many CMA projects
{% endhint %}

Use non-overlapping ports is a feature that will tell CMA when choosing available ports on the system to also ignore ports that are already used by other CMA instances, even if they are stopped.\
That way it will ensure that your projects will not get new ports every time you switch between them.

To enable this feature, set `useNonOverlappingPorts` field in the system configuration file to `true`.

### Analytics

Analytics helps us to collect data about errors or possible slow-downs and helps us to identify areas that should be fixed or improved!

Of course, you have an option to opt out of analytic data collection. To do that set `analytics` field in the system configuration file to  `false` and CMA will not collect analytic data from your system.
