# Introduction

<Note>
  **FastFlags** are internal, configurable settings that allow Korone developers to remotely enable, disable, or adjust features and engine behavior without requiring a full software update.
  Users can modify these flags to unlock hidden engine settings, potentially improving performance or altering game features.
</Note>

With koroneStrap, you can apply FastFlags to Korone!

## Accessing FastFlags Configuration

To configure FastFlags, select option **5** (Set FastFlags) from the koroneStrap main menu. This will open the FastFlags Configuration interface.

## Managing FastFlags

The FastFlags Configuration menu provides several options for managing your FastFlags:

### 1. Add FastFlag

Add a new FastFlag to your configuration. You'll need to specify:

* The FastFlag name
* The FastFlag value
  <Tip>Find FastFlags with [our dedicated page](/koroneStrap/fastflags/finding-fastflags)</Tip>

### 2. Remove FastFlag

Remove an existing FastFlag from your configuration.

### 3. Clear all FastFlags

Remove all configured FastFlags at once. Use this option to reset your FastFlags configuration.

### 4. Apply FastFlags

Apply your configured FastFlags to Korone. This writes your FastFlags configuration and makes it active.

### 5. Import FastFlags from JSON

Import a FastFlags configuration from a JSON file. This is useful for:

* Applying pre-configured FastFlag sets
* Sharing configurations between installations
* Backing up and restoring your FastFlags
