# Using process flow labels
## Introduction
Existing process flow labels can be [applied](#applying-labels-to-a-process-flow) and [removed](#removing-labels-to-a-process-flow) for a process flow via process flow settings. You can define labels for any purpose - there's no right or wrong way to use them. For example, you might define labels to indicate the development status of a flow, whether it's a '[master' flow for virtual environments](https://doc.wearepatchworks.com/product-documentation/virtual-environments/implementing-virtual-environments/creating-a-master-process-flow), etc.
As the number of process flows grows for your organisation, it can also be useful to [filter the main process flows list by specific labels](#filtering-process-flows-by-label).
## Applying labels to a process flow
{% stepper %}
{% step %}
**Access the required process flow**
[Ac](https://doc.wearepatchworks.com/product-documentation/process-flows/accessing-your-process-flows)[cess the process flow](https://doc.wearepatchworks.com/product-documentation/process-flows/accessing-your-process-flows) that you want to update.
{% hint style="info" %}
Labels are associated with the process flow as a whole, not a specific version. As such, it doesn't matter which version of the process flow you display on the canvas to make this update.
{% endhint %}
{% endstep %}
{% step %}
**Open process flow settings**
Click the 'cog' icon in the [canvas](https://doc.wearepatchworks.com/product-documentation/process-flows/building-process-flows/the-process-flow-canvas) toolbar to access settings for this process flow:
{% endstep %}
{% step %}
**View existing labels**
Click in the `labels` field - for example:
{% hint style="info" %}
If you don't see a label that you need, use the `create label` option to [add it now](https://doc.wearepatchworks.com/product-documentation/process-flows/managing-process-flows/process-flow-labels/adding-new-process-flow-labels).
{% endhint %}
{% endstep %}
{% step %}
**Apply the required label(s)**
Select any labels that you want to apply (you can add a single label or multiple labels at the same time):
{% endstep %}
{% step %}
**Save settings**
Save settings when you've finished making updates.
{% endstep %}
{% endstepper %}
## Removing labels from a process flow
{% stepper %}
{% step %}
**Access the required process flow**
[Ac](https://doc.wearepatchworks.com/product-documentation/process-flows/accessing-your-process-flows)[cess the process flow](https://doc.wearepatchworks.com/product-documentation/process-flows/accessing-your-process-flows) that you want to update.
{% hint style="info" %}
Labels are associated with the process flow as a whole, not a specific version. As such, it doesn't matter which version of the process flow you display on the canvas to make this update.
{% endhint %}
{% endstep %}
{% step %}
**Open process flow settings**
Click the 'cog' icon in the [canvas](https://doc.wearepatchworks.com/product-documentation/process-flows/building-process-flows/the-process-flow-canvas) toolbar to access settings for this process flow:
{% endstep %}
{% step %}
**Remove labels**
Move down to the labels panel and click the 'cross' icon associated with any labels that you want to remove. For example:
{% endstep %}
{% step %}
**Save settings**
Save settings when you've finished making updates.
{% endstep %}
{% endstepper %}
## Filtering process flows by label
Any labels that have been applied to process flows are displayed in the [main process flows list](https://doc.wearepatchworks.com/product-documentation/process-flows/accessing-your-process-flows) - for example:
To filter this list by specific labels, follow the steps below.
{% stepper %}
{% step %}
**Access filter options**
Click the `filter` icon associated with the `labels` column:
Filter options are displayed:
{% endstep %}
{% step %}
**Choose labels for the filter**
Click in the `select labels` field and select the label(s) that you want to apply for filtering. The list of flows updates immediately to reflect your selections, for example:
{% endstep %}
{% endstepper %}
