Using YAML as the base configuration format allows me to define structured defaults that are easy to read, maintain, and version-control. Environment variables then handle dynamic values for environment-specific customisations, with custom logic to support default values for additional flexibility.

In many places in KeePass (auto-type, URL field, triggers, ...), placeholders can be used.

• Entry Field Placeholders
• Entry Field References
• Paths and Date/Time Placeholders
• Environment Variables
• Text Transformations
• Other Placeholders
