# How to Configure Variables

Variables are the user defined fields that:

* can have any desirable name
* can have value of String type
* can be inserted anywhere as Merge field
* can be updated by Actions
* are initialized with initial values when Kanban page is loaded or reloaded
* are stored in memory and do not changed when Kanban is refreshed by Kanban API or "Refresh Kanban" button (and this is a perfect tool to dynamically change a lot of Kanban properties)

Variables are configured in the proper section of Kanban Properties sidebar. Click "edit" link to show a proper popup.

{% hint style="warning" %}

Notes:

* Variable Name can not contain special symbols.
* Variable Name in some cases will be transformed to lowercase by system. No problem, variable names are not case sensitive.
  {% endhint %}

Save variables. After being variables will be listed in "Variables" section:

To see what values are stored in the variables, and manipulate with them, user can open a [Debug Console](https://docs.flexikanban.ai/standard-kanban/using-kanban/how-to-debug-a-kanban) on Kanban. To know how to work with variables [see proper article](https://docs.flexikanban.ai/standard-kanban/using-kanban/how-to-work-with-variables).
