The Skills Network Toolbox is a built-in extension that helps you efficiently and easily interact with a number of technologies inside the Skills Network Cloud IDE. Some of these features include the ability to launch MySQL, PostgreSQL, MongoDB, Cassandra, & Apache Airflow from the click of a button. Additionally, the admin tools phpMyAdmin (for MySQL), pgAdmin (for PostgreSQL), mongo-express (for MongoDB), and Airflow Webserver (for Apache Airflow) are available in these environments. 

To open the Toolbox, click the Skills Network logo on the left sidebar. You will see a number of dropdowns that you can explore. Click on your selected database or application within the dropdown and hit the Start button to launch it.
