In this video, Jan de Vries explains how the team server enables you to collaborate with your team in order to build awesome apps.
The Team Server is the Mendix host environment that hosts all your applications. It also facilitates versioning of apps, allowing for team members to sync updated projects.
Using the Desktop or Web Modeler, team members can build a local, working copy of the application and then commit changes to the Team Server online repository.
This makes working on features, bugs or other items as a team, intuitive and simple.
