Below are frequently asked questions about using the ULDA library for secure data management.

• Q: How do I obtain an API key for ULDA?
  A: Visit the 0 AM Admin Portal, sign in or create an account, and generate an API key in the API Keys section. Store it securely in environment variables.

• Q: Why must master and content file names be unique?
  A: Master file names must be unique within an API key to prevent conflicts. Content file names must be unique within a master file to ensure proper organization and access.

• Q: How do I set up real-time updates with WebSockets?
  A: Use methods like connectToUpdateContentFile to listen for events (e.g., content:update). Ensure your Ulda instance is initialized with the correct apiUrl (default: https://api.0am.ch).
