# About Extension Kit Core

## What is Extension Kit Core

Extension Kit Core is a no-code add-on that offers a powerful set of functionalities that enhance the implementation and usage of M-Files. It is developed with years of experience and knowledge in M-Files, as well as with a keen understanding of customer requirements and objectives for efficient content management.

As a Vault Application Framework (VAF) application, Extension Kit Core is installed to a vault as any other M-Files add-on.

Comprising over 20 modules accessible through the M-Files Admin tool, Extension Kit Core offers various extended M-Files capabilities configurable without the need for custom development, ensuring that the M-Files implementations are less prone to errors. Through the enhanced quality of implementation, faster configuration, and additional functionalities, Extension Kit Core elevates the overall M-Files experience.

## How Extension Kit Core works

Extension Kit Core works on a trigger-action principle, meaning it is based on actions that are triggered by events in M-Files. It supports reacting to the following events (triggers):

- Object created
- Object changed
- Object metadata changed
- Object changed state
- Object entered state
- Object left state
- Object deleted
- Object destroyed
- On comment
- Scheduled
- RunOnce
- Orchestrated
- Button click
- File changed
- File added
- File removed

To create a trigger-based action, Extension Kit Core users configure rules within a particular module, specifying trigger events in M-Files, additional conditions for rule activation, and actions that will happen as a result.

For more details on how to get started by creating a rule, refer to [How to Create Rules](https://extensionkit.unitfly.com/documentation/how-to-create-rules/).
