Customizing DAG UI Header and Airflow Page Titles
=================================================

Airflow now allows you to customize the DAG home page header and page title. This will help
distinguish between various installations of Airflow or simply amend the page text.

Note: the custom title will be applied to both the page header and the page title.

To make this change, simply:

1.  Add the configuration option of ``instance_name`` under ``webserver`` inside ``airflow.cfg``:

.. code-block::

  [webserver]

  instance_name = "DevEnv"


2.  Alternatively, you can set a custom title using the environment variable:

.. code-block::

  AIRFLOW__WEBSERVER__SITE_TITLE = "DevEnv"
